The animation at left shows street grid development from 1801 to 2011, mapping Manhattan’s gradual expansion north. The animation at right shows the population density over time of each census tract in Manhattan. Notice how Manhattan’s population density rises and peaks around 1900 before falling to present levels. Despite Manhattan’s appearance of being denser and more built up with skyscrapers than ever before, the island actually has a lower population density than a century ago.
Before the introduction of subways in the early twentieth century, the difficulties of commuting distances over land and water drove a denser form of urbanism than today. By 1900, the island of Manhattan had over 2.3 million residents in comparison to only 1.6 million in 2020. These people were crowded into dense blocks with upward of half a million people per square mile. The subways had not yet opened, suburban sprawl had not yet arrived, there were no rail connections under the Hudson River, and Manhattan had few or no road connections with the other boroughs and the mainland. This produced an island of remarkable density with the Lower East Side the densest place on earth, while only a few miles north, Harlem remained almost rural.
In 1903, the Williamsburg Bridge over the East River linked the Lower East Side with undeveloped Brooklyn. The trolley lines, subways, and roadway that stretched over the Williamsburg accelerated the development of Brooklyn, first in the higher density parts of Brooklyn closest to Manhattan and later to the distant parts of Brooklyn and Queens with suburban population densities. Suburban growth started earlier than the 1950s image of Levittown, and with the movement of people outwards from Manhattan, the centers of immigrant cultural life shifted, too. In every following year, the Lower East Side lost people, arriving at a density in 2020 only a sixth of what it was in 1900.
Over the following decades, improvements in public transportation and the introduction of the car “smoothed” out the population density. At the same time, Manhattan’s street network expanded to cover the whole of the island from end to end. As the subways made commuting easier, people no longer need to live within walking distance of where they worked. As a result, many industries remained in Manhattan while their workers moved to other boroughs, and later still to the more distant suburbs. As a result, the population densities of Manhattan today are more consistent from one end of the island to the other. Unlike in 1900, Harlem today is about as dense of the Lower East Side because transportation has made one part of the island almost as accessible to work as any other part of the island.
This animation illustrates Manhattan specifically, but Manhattan’s growth and population densities were influenced by larger population and technology changes in the New York region.
This film traces Detroit’s evolution from its origins as a French trading post in the 1700s, to its explosion as a metropolis, followed by its precipitous decline as a symbol of America’s post-industrial urban landscape. The film weaves in details about the city’s politics, population, and technology – all of which influenced the city’s geography and built environment. At each phase in urban history, the built environment grew and was modified in direct response to political events like racial segregation, population changes like the Great Migration, technology developments like the mass-produced car, and government interventions like urban renewal.
The animation tells the story of Detroit specifically and the story of American cities more broadly. To varying degrees, the path of Detroit’s development mirrors hundreds of other smaller cities and towns scattered across the American Northeast and Midwest. No other American city witnessed as large a population loss, as dramatic 1960s racial unrest, or as radical a transformation from symbol of progress into symbol of decay. To a lesser degree, other places in America followed Detroit in lockstep. Urban renewal projects, highway construction, racial tensions, suburban growth, and infrastructure under-investment happened across America, and in parallel to Detroit.
However, the most dramatic transformation of Detroit is left unwritten in this film. Beneath the surface-level events of political conflict and urban change, the largest event in Detroit is not unique to Detroit. As filmmaker Godfrey Reggio describes, the most important theme in the history of civilization is “the transiting from all nature, or the natural environment as our hosts of life for human habitation, into a technological milieu into mass technology as the environment of life.” European cities developed slowly and gradually over centuries, in the process removing all memory of the natural landscape before civilization. American cities are unique in their youth and speed of growth. They are new enough that an active memory survives through place names and written records of the landscape and indigenous peoples who lived there before colonization. As the oldest colonial settlement west of the Appalachians, and as the city that perfected the mass-produced automobile, Detroit becomes the prime symbol of man’s transformation of his home from a natural world into a technological society removed from nature.
The accompanying music is by composer Philip Glass and was written for Godfrey Reggio’s 1982 experimental documentary Koyaanisqatsi. The shifting layers and repetitive phrases of Glass’ music accompany Reggio’s montages of natural landscapes, factory assembly lines, and chaotic city streets. Koyaanisqatsi means “life out of balance” in the language of an indigenous American tribe called the Hopi. In the original documentary, Glass’ music was paired with scenes of desolate streets in the South Bronx, the abandoned Pruitt-Igoe public housing in St. Louis, and ruined skyscrapers falling in slow motion. In my reinterpretation of Glass’ music, the imagery is now of Detroit in maps. The pace and events in the animation are tied to the structure of the music. As the volume and speed of the music increase and decrease, so too does the growth and decline of Detroit.

The influx of black people during the Great Migration and the outflow of cars from Detroit’s factories reshaped the city’s built environment and the American public’s perception of Detroit. Detroit is now thought of as a majority-black city surrounded by majority-white suburbs. Today, 83% of Detroit’s population is black, and only 11% is white. But the graph above shows that Detroit was majority-white until the 1980 census. For most of its history, Detroit was 95 to 99% white. Today, the majority of the metro region’s population lives in the suburbs that surround Detroit. But until the 1960 census, the majority of the population lived within the city limits. Today, Detroit is so reliant on the car that it has no commuter rail network, no subways, and limited public transportation options. But until the 1950s demolition of Detroit’s light rail network, a majority of residents lived within walking distance of a light rail station for commuting. Detroit’s demographics, suburban sprawl, and transportation options have all flipped in the past century. From a high-density, transportation rich, and majority-white city in 1920, Detroit has become a low-density, transportation poor, and majority-black city in 2020.
A lot of people say Detroit has terrible public transit design. But from the perspective of car companies, the real estate lobby, and fearful whites, the system does exactly what it was intended to do: to segregate and divide our country by covert means long after Jim Crow officially “ended.” Failure by design. The failure of Detroit is, in large part, planned and a consequence of government policy decisions that: prioritize suburban growth over urban development; benefit suburban whites over urban blacks; and encourage private cars at the expense of public transit.
As the Detroit Evolution Animation plays, the map key on the lower right hand corner indicates Detroit’s demographics at each decade in history. Try to link changes to demographics with changes to the urban form. Ask yourself the questions: How were technology, transportation, and demographic changes imprinted on the built environment? How does the built environment, in turn, shape urban and suburban life?

1. Construction time-lapse
This construction time-lapse illustrates the history of Notre-Dame from c.1060 to the present day, following ten centuries of construction and reconstruction. The film was created in the computer modeling software SketchUp, based on hand-drawn image textures. The ink drawings of nineteenth-century architect Viollet-le-Duc were scanned and applied to the model surfaces, as if to transform the two-dimensional artwork into the three-dimensional digital. I believe computer models should have a certain handmade quality.

The converging and ongoing crises of COVID-19, climate change, radical economic inequality, pervasive racism, and racist violence require that all systems, infrastructures, and institutions, including architecture, space, and cities, be reimagined. This reimagining must include how and to what ends architecture, landscape architecture, and urban design can act in the world.
This workshop, organized by The Architectural Leagueof New York, brought architects, planners, and historians in conversation to listen to each other, identify critical issues, and develop ideas about what might and should be done.
After the virus ends, millions will become used to – and even prefer – work from home. Employers downsize offices. Fewer people commute by car. Our now overbuilt highways and airports will be restored to nature.
Now thousands of vacant offices and buildings will be too expensive and energy inefficient. Abandoned towers, malls, airports, and arenas will become ruins, a modern Acropolis.
Instead of flying to Europe, eco-friendly tourists visit this new “Museum to American Civilization.”
Demolished highways and buildings in flood zones will become landfill. The sedimentary layers in these landfill mountains will be a geological history of American civilization in the Anthropocene.

This two minute time-lapse reconstructs the 400 year evolution of Lower Manhattan’s skyline. Watch as the city evolves from a small village into a glistening metropolis.
This is also a film about the history of technology. Changing methods of representing urban space influence our perception of time and the city. When New York City was founded, Dutch settlers captured their town’s appearance through seventeenth-century drawings and paintings. As the city grew, people started using printing presses to reproduce images of the city in the eighteenth and nineteenth centuries. In the twentieth century, photographers started capturing their city from above through aerial photos. For the first time, New Yorkers could view the entire city in a single panoramic photo.
In tribute to this long artistic tradition, this film constructs the city as each generation of New Yorkers would have represented it: through the subsequent technologies of drawing, printing, photography, and film.

In 1872, Eugène-Emmanuel Viollet-le-Duc, the French author and architect celebrated for restoring Notre-Dame of Paris, wrote in his Lectures on Architecture that the form of the Gothic cathedral was the synthesis of the early Christian basilica and the Romanesque three-aisled church. In this analysis, Viollet-le-Duc reasoned that a thesis (early Christian) plus an antithesis (Romanesque) produced the synthesis (Gothic).
Animation from Stephen Murray
Although the history and origins of Gothic are more complex than Viollet-le-Duc’s formula, this formula provides a method to dissect the Renaissance and Enlightenment counterpart to the medieval cathedral: the Greco-Roman basilica, as embodied by St. Paul’s Cathedral, constructed from 1675 to 1711 by Christopher Wren (1632-1723). St Paul’s is a symbol of Enlightenment-era London, built to rival its medieval counterpart of Westminster Abbey.
In this essay, and in my analysis of this neoclassical cathedral, I will parallel Viollet-le-Duc’s analysis of the medieval church. The thesis is that St. Paul’s is a work of techno-scientific engineering. The antithesis is that this building is a work of art that speaks to the larger cultural moment of Enlightenment London. The synthesis is the dome of St. Paul’s that merges these two forces of engineering and art into a unified and impressive creation.
Thesis: ENGINEERING The engineering of this dome is more complex than meets the eye.
In this animated construction sequence, view how the dome was engineered.
St. Paul’s Cathedral features an innovative triple dome structure. On the circular drum, the inner dome rises and is visible from the cathedral interior. Above this inner dome, a brick cone rises to support the 850 ton lantern. This brick cone also supports the wood rafters and frame of the outer dome, which is covered in wood and lead. This three dome system allows the cathedral to support such a heavy lantern, all the while maintaining the great height needed to be a visible London landmark.
Inner dome – visible from inside and purely for show; height 225 ft (69m)
Middle brick cone – a brick cone that is invisible from below but supports the 850 ton lantern above; height 278 ft (85m)
Outer dome – a wood and lead-roofed structure visible from the cathedral exterior; height 278 ft (85m)
Lantern – an 850 ton stone lantern and cross, whose weight is carried to the ground via the middle brick cone 365ft (111m)
The inner and outer domes are decorative, while the brick cone is the true weight-bearing support. The model below is created from measured plans and is accurate to reality.

Antithesis: ART The cathedral’s location and design reflects its cultural-historical moment of the Enlightenment.
The 1666 Fire of London turned the thirteenth-century medieval cathedral of old St. Paul’s into a charred ruin. As masons demolished the ancient ruins, the opportunity arose to erect a new cathedral designed around new cultural reference points: neoclassical instead of medieval, Protestant instead of Catholic, and with steel and brick instead of stone alone. St. Paul’s reveals what was, for the time, novel ways of thinking about space.
There are three main ways this cathedral architecture reflected its time period.
Firstly, this cathedral embodied an emerging understanding of artist and architectural space. The burned medieval cathedral was built over centuries by numerous masons in collaboration, whose names are forgotten. New St. Paul’s was built in one uninterrupted sweep by a single architect, whose name and biography are known in detail. It was only during the Renaissance and Enlightenment that society began to think of art and architecture as the product of an individual artist’s personality and ambitions. The engineer, artist, and architect were elevated above nameless masons. Historians can describe the relationship between artist and artwork with a degree of detail impossible to attribute to the architects of older, medieval cathedrals. It is to this period in the history of science and philosophy that historians also attribute the cult of personality surrounding individual artistic genius. Also central to the Enlightenment period was the organization and standardization of all human knowledge into encyclopedias and libraries, much in the way that St. Paul’s was centrally planned, designed, and coordinated with more precision than survived from the sporadic organization of medieval cathedrals and monastic libraries.

The irony is that for a building that appeared modern to eighteenth-century eyes, the construction methods with scaffolding and wooden winches to lift heavy stones were mostly unchanged from centuries before. The wooden rafters inside the cathedral roof are from trees planted hundreds of years before during the High Middle Ages. Most telling of all, the vaults of the nave and choir are supported by medieval-style flying buttresses. Fearing that flying buttress – an engineering technique deeply associated medieval architecture – would be inappropriate to a classical basilica, Wren hid these buttresses behind a screen wall. Modern or medieval? The building methods and religious traditions largely descended from late medieval methods, even if the building exterior evoked an opposed classical tradition.
Secondly, this cathedral reflected Britain’s growing interest in European and world affairs. Merchant ships sailing up the River Thames would first see the domes of Wren’s Greenwich Hospital for the wounded and retired sailors in the British navy; around the next bend in the river, the dome of St. Paul’s came into view. With Britain competing with France for colonial power, Wren visited Les Invalides, the Paris hospital for retired sailors in the French navy. Through studying Les Invalides and reviewing prints of French architecture, Wren copied and improved on classical traditions when redesigning London after the fire. St. Paul’s is also similar to Michelangelo’s sixteenth-century dome at the Vatican. St. Paul’s was supposed to be a cathedral, but its dome became an act of one-upsmanship against similar and existing domes in Paris and Rome.

Lastly, this religious architecture ironically symbolized the growing power of secular thought and finance over national governance. As capital of England, London’s architectural focal points are split geographically between Westminster to the west and central London to the east. Power in Westminster is, in turn, divided between three main architectural points of interest: Westminster Abbey (symbolizing God), Buckingham Palace (symbolizing the king), and the Houses of Parliament (whose House of Commons symbolizes the country). This maps onto the neat triad of “God, King, and Country” or the three estates of “clergy, nobility, and commoners.”
However, the location of St. Paul’s, in the center of London’s financial district and near the commercial hub of the Royal Exchange, competed with Westminster Abbey in size and height. It were as if the commercial interests of bourgeois merchants and industrialists working in central London were competing with and questioning the traditional balance of power between the king, clergy, and nobility that had excluded the merchant middle classes from power. It was as if this cathedral’s architecture asserted the growing importance of London’s businesses and financial district for the governance of a country. Fittingly, as if proof of their success, zoning laws and building height restrictions in much of London are still designed for miles around so as to preserve the visibility of St. Paul’s. Wren was no opponent to the monarchy, and the construction of St. Paul’s, in fact, benefited from royal support. Nonetheless, the architecture still speaks to the eighteenth-century tension between ancient traditions and modern technologies.
Protected vistas radiating out from Westminster and St. Paul’s. The cathedral architecture becomes, in equal parts, the symbolic, physical, and cartographic center of urban life, as if the red lines on these maps were arrows directing our gaze to the center of power.
Construction was funded through a tax on the coal London residents and businesses consumed. In later years, coal became a polarizing symbol of both the dirty, soot-covered injustices of urban poverty and the techno-scientific progress fueling Britain’s Industrial Revolution. Fittingly, the same dark ingredient that powered Britain’s industrial looms and colonial power also funded construction of the cathedral that came to symbolize London and the empire. St. Paul’s is a church, but its neoclassical design and secular location allow it to become much more than just a church.
Synthesis: ENGINEERING AND ART This dome is a synthesis of art and engineering.
In addition to St. Paul’s political and cultural symbolism, this dome also synthesized the most recent advances in building (industrially manufactured brick) with simultaneous techno-scientific discoveries. This cathedral embodied the core beliefs of European Enlightenment thought: the application of science to advance society and the synthesis of Greco-Roman aesthetic traditions with modern technologies.
Parabolic behavior of an unweighted chain
In the years St. Paul’s was under construction, Wren corresponded with his polymath, scientist, and mathematician friend Robert Hooke (1635-1703). From Hooke’s empirical experiments with springs, strings, and weights (see Hooke’s Law), he confirmed that an unweighted chain suspended between two points would form a parabolic curve. Furthermore, the quadratic formula Y = X2 mathematically expressed and modeled the chain’s behavior. Math and reality were, in one formula, linked.
There is effectively no limit to how much weight a chain can hold in tension. A suspension bridge roadway weighs hundreds of thousands of tons, but the steel cables suspending it are usually no thicker than a few centimeters. However, these cables will collapse under the slightest amount of compression.
In contrast to a chain that is strong under tension but weak under compression, stone is the opposite: strong under compression but weak under tension. Imagine the incredible compressive forces of the earth’s crust that compress ancient sand and fossils into solid limestone. When masons quarried this stone into blocks, they were challenged to design cathedrals that minimized any tension on stone. Tension in the horizontal span of the cathedral vault, for instance, caused structural collapse. In response, masons devised flying buttresses and complex structural interventions to prevent stone from cracking under tension.
The genius of Enlightenment architects like Wren stems from their ability to deduce: If a suspended chain formed a parabolic curve in pure tension as modeled by Y = X2, then the converse statement must also be true: A stone arch modeled on a parabolic curve would act in pure compression, as modeled by the reverse equation -Y = X2. Thus, by mathematical logic, the downward and tensile force of chains mirrored the upward and compressive forces of stone. Spanish architect Antoni Guadí (1852-1926) observed similar phenomena when designing his final project, the Basilica of Sagrada Familia in Barcelona (begun 1883). Without the benefit of computer models, Guadí suspended weighted strings from the ceiling and then viewed these creations in a mirror, so as to deduce the optimal geometric form for his cathedral vaults.

models the form of the ideal dome
Knowing this, Wren constructed the dome as a brick cone similar in shape to a parabolic arch. Around the base of the dome, where the buckling forces of tension were greatest, Wren inserted bands of steel chain the circumference of the dome. Medieval masons intuited this, too, when they designed pointed arches whose shape was somewhat closer to a parabola than was the traditional and older Roman arch. However, while medieval masons at places like Amiens Cathedral relied on trial and error with few benefits of scientific thought, Wren relied on science and math to deduce the ideal form. Thus, the brick middle dome is only nine inches thick, but it supports a lantern above that weighs 850 tons.
Wren was more than a mathematician. He also had a keen aesthetic eye from close study of French and classical architecture. His white limestone buildings all drew inspiration from the classical traditions of Greece and Rome. However, although the brick cone was cheaper, stronger, and used fewer materials than a traditional stone dome, Wren knew that a brick architectural form was too radically modern to leave exposed, and too aesthetically different from the otherwise neoclassical church. Wren therefore hid the true, weight-bearing brick cone. Outside the brick cone, Wren added a lead and wood roof that supported no weight and was in no way connected to the lantern it seemed to support. Inside the brick cone, which was too steep and too tall to paint a convincing ceiling mural on, Wren erected a decorative arched vault within that was merely a decorative surface for James Thornhill’s paintings.
Art and engineering, religion and politics, tradition and innovation were, through the design of one dome, linked. Wren might not have intended to inject his cultural-historical moment into the design. As an architect-engineer, he was inventing the most stable and economic way to cover the cathedral. However, the implications of this engineering reflected the spirit of the city and society at large.
Eastern State Penitentiary was completed in 1829 in northwest Philadelphia, Pennsylvania by architect John Haviland. It was reported as the most expensive and largest structure yet built in America.
The design featured a central guard tower from which seven cell blocks radiated like a star. This system allowed a single guard to survey all prisoners in one sweep of the eye. A square perimeter wall surrounded the entire complex – thirty feet high and twelve feet thick. The decorative entrance resembled a medieval castle, to strike fear of prison into those passing. This castle contained the prison administration, hospital, and warden’s apartment.
As we approach the central tower, we see two kinds of cells. The first three cell blocks were one story. The last four cell blocks were two stories. Here we see the view from the guard tower, over the cell block roofs and over the exercise yards between cell blocks. Each cell had running water, heating, and space for the prisoner to work. Several hundred prisoners lived in absolute solitary confinement. A vaulted and cathedral-like corridor ran down the middle of each cell block. The cells on either side were stacked one above the other. Cells on the lower floor had individual exercise yards, for use one hour per day. John Haviland was inspired by Jeremy Bentham’s panopticon. (Don’t know what the panopticon is? Click here for my explanation.)
Over its century in use, thousands visited and admired this design. An estimated 300 prisons around the world follow this model – making Eastern State the most influential prison ever designed.

Shows prison as it appeared in the period 1836 to 1877 before later construction obstructed the original buildings.
Eastern State Penitentiary’s exterior resembles a medieval castle. More than a random choice, the qualities of Gothic attempt to reflect, or fall short of reflecting, the practices of detention and isolation within. Contrary to the claim often made about this structure that the appearance was supposed to strike fear into passerby, the use of Gothic is in many ways unexpected because of its untoward associations with darkness and torture, which the prison’s founders were working to abolish. It is therefore surprising that America’s largest and most modern prison should evoke the cruelties and injustices of the medieval period. The choice of Gothic appearance, and the vast funds expended on the external appearance few inmates would have seen, leads one to question the audience of viewers this penitentiary was intended for – the inmates within or the public at large?
This essay responds by analyzing what the Gothic style represented to the founders. The architectural evocation of cruelty and oppression was, in fact, not contradictory with the builders’ progressive intentions of reforming and educating inmates. This prison’s appearance complicates our understanding of confinement’s purpose in society. The two audiences of convicted inmates and tourist visitors would have received and experienced this prison differently, thereby arriving at alternative, even divergent, understandings of what this prison meant. More than an analysis of the architect John Haviland and of the building’s formal qualities in isolation, this essay situates this prison in the larger context of Philadelphia’s built environment.

Abstract: The Berlin Evolution Animation visualizes the development of this city’s street network and infrastructure from 1415 to the present-day, using an overlay of historic maps. The resulting short film presents a series of 17 “cartographic snapshots” of the urban area at intervals of every 30-40 years. This process highlights Berlin’s urban development over 600 years, the rapid explosion of industry and population in the nineteenth-century, followed by the destruction and violence of two world wars and then the Cold War on Berlin’s urban fabric.

Methodology and Sources
I chose not to represent urban development before 1415 for three reasons: Firstly, there are too few accurate maps of the city before this time. Secondly, I needed to find accurate maps that had visual style consistent with later years, to enable easier comparison of development over time. Thirdly, the extent of urban development and population is limited (fewer than 10,000 Berliners).
There are numerous maps showing Berlin’s urban growth. Yet, few of them are drawn to the same scale, orientation and color palette. This makes it more difficult to observe changes to the city form over time. Fortunately, three map resources show this development with consistent style.
The Historischer Atlas von Berlin (by Johann Marius Friedrich Schmidt) published 1835 represents Berlin in the selected years of: 1415, 1648, 1688, 1720, 1740, 1786. This atlas is available, free to view and download, at this link.
After the year 1786, I rely on three books from cartographer Gerd Gauglitz:
Berlin – Geschichte des Stadtgebietsin vier Karten Contains four maps of Berlin from 1806, 1920, 1988 and 2020. Read article. Berlin – Vier Stadtpläne im Vergleich Contains four maps from 1742, 1875, 1932 and 2017. Read article. Berlin – Vier Stadtpläne im VergleichErgänzungspläne Contains four maps from 1840,1953, 1988 and 1950. The last map from 1950 is speculative and shows Berlin as it would have looked had Germany won WWII and executed Albert Speer’s plans for rebuilding the city, named “Germania.” Read article.

Below is an interactive map I created of the Berlin Wall’s route and the four Allied occupation areas:
Population statistics in the 17 “cartographic snapshots” are estimates. The historical development of Berlin’s population is known for a few years. For other years, the population is estimated with regards to the two censuses between which the year of the “snapshot” falls.
Postmodernist thinkers, like Michel Foucault, interpret Jeremy Bentham’s panopticon, invented c.1790, as a symbol for surveillance and the modern surveillance state.
This lecture is in two parts. I present a computer model of the panopticon, built according to Bentham’s instructions. I then identify design problems with the panopticon and with the symbolism people often give it.
To say all in one word, it [the panopticon] will be found applicable, I think, without exception, to all establishments whatsoever, in which, within a space not too large to be covered or commanded by buildings, a number of persons are meant to be kept under inspection.
– Jeremy Bentham
Since the 1790s, Jeremy Bentham’s panopticon remains an influential building and representation of power relations. Yet no structure was ever built to the exact dimensions Bentham indicates in his panopticon letters. Seeking to translate Bentham into the digital age, I followed his directions and descriptions to construct an exact model in virtual reality. What would this building have looked like if it were built? Would it have been as all-seeing and all-powerful as Bentham claims?
Central to Bentham’s proposed building was a hierarchy of: (1) the principal guard and his family; (2) the assisting superintendents; and (3) the hundreds of inmates. The hierarchy between them mapped onto the building’s design. The panopticon thus became a spatial and visual representation of the prison’s power relations. As architectural historian Robin Evans describes: “Thus a hierarchy of three stages was designed for, a secular simile of God, angels and man.”

To his credit, Bentham recognized that an inspector on the ground floor could not see all inmates on the upper floors. The angle of view was too steep and obstructed by stairs and walkways. To this end, Bentham proposed that a covered inspection gallery be erected between every two floors of cells.
By proposing these three inspection galleries, Bentham addressed the problem of inspecting all inmates. However, he created a new problem: From no central point was it now be possible to see all activity, as the floor plans below show. The panoramic view below shows the superintendent’s actual field of view, from which he could see into no more than four complete cells at a time. The view from the center was not, in fact, all-seeing. Guards would have to walk a continuous circuit round-and-round, as if on a treadmill. They, too, are prisoners to the architecture.

The intervening stairwells and inspection corridors between the perimeter cells and the central tower might have allowed inspectors to see into the cells. Yet these same architectural features would also have impeded the inmates’ view toward the central rotunda. Bentham claimed this rotunda could become a chapel, and that inmates could hear the sermon and view the religious ceremonies without ever needing to leave their cells. The blinds, normally closed, could be opened up for viewing the chapel.

Bentham’s suggestion was problematic. The two cross sections above show that, although some of the inmates could see the chapel from their cells, most would be unable to do so.
In spite of all these obvious faults in panopticon design, Bentham still claimed that all inmates and activities were visible and controlled from a single central point. When the superintendent or visitor arrives, no sooner is he announced that “the whole scene opens instantaneously to his view,” Bentham wrote.

Despite Bentham’s claims to have invented a perfect and all-powerful building, the real panopticon would have been flawed were it built as this data visualization helps illustrate. Although the circular form with central tower was chosen to facilitate easier surveillance, the realities and details of this design illustrate that constant surveillance was not possible. That the British public and Parliament rejected Bentham’s twenty year effort to build a real panopticon should be no surprise.
However flawed the architecture, Bentham remained ahead of his time. He envisioned an idealistic and rational, even utopian, surveillance society. Without the necessary (digital) technology to create this society, Bentham fell back on architecture to make this society possible. The failure of this architecture and its obvious shortcomings do not invalidate Bentham’s project. Instead, these flaws with architecture indicate that Bentham envisioned an institution and society that would only become possible through new technologies invented hundreds of years later.
