Of all the designs prepared by Adam for the Bridewell, this is the most advanced for which drawings still exist. It is this version which correctly and most fully implements Jeremy Bentham's Panopticon concept for prison design. In fact the idea of invisible inspection is implemented in so many places in this design that, had it been built, it would have resulted in a very high security prison.

The design consists of four blocks linked by circulation spaces within an arrangement of exercise yards contained within a perimeter wall with a single entrance gate. Of the three blocks to the South (Figs 1-3 top edge of the drawings) the East wing is a Bedlam, the West an Infirmary. The two side wings mirror each other about the north-south axis of the larger central block, which is the prison proper. The various classes of prisoners this was intended for can be ascertained, as in the other designs, from the titles given to the various exercise courtyards. These are labled clockwise from the courtyard on the furthest East (left) side :-

Yard for Bedlamites
Yard for Women
Yard for Debtors
Yard for Felons
Yard for Convicts
Bridewell Yard for Idle Men and Youth
Yard for the Infirmary

The remaining courtyards are not labled.

The forth block on the North side nearest the entrance gate is the Governor's House.

As with Version 2 the geometric arrangement of the exercise yards and the perimeter wall is symmetrical about a North South axis, in this case forming a kind of irregular octagon.

Roof Plan

Fig 1.  Roof Plan showing roof lights over the open full height half cylinder spaces - which occur in each of the three cellblocks. The upper (fifth) level of cells is separate from the main atrium space and has a row of rooflights over.

Upper Floor Plan

Fig 2 - Upper Level A single gatehouse with guard room on the North side is the only entry to the prison. On the north side of the courtyard steps lead up to the Governors entrance and down to the prison entrance. The blocks are linked by corridors, within which are stairs giving access to all levels

Ground Floor Plan

Fig 3 - Ground Floor and Courtyards. The shape of the eight-sided enclosure wall could easily be adjusted to respond to irregularities of the site on the edge of a cliff. On the external perimeter at each change of angle is a defensible position. Internal walls divide the spaces between the buildings intoexercise courtyards

Basement Plan

Fig 4 - Basement plan. Guards and prisoners descended stairs in the centre of the building to separate underground passages leading under the cells to exercise yards to the South of the building. The plan at this level also shows punishment cells (without light) and the boiler room for the building. This drawing belongs to CSv4. It is included here because this design has a similar arrangement.

At the heart of this design is the implementation of Jeremy Bentham's Panopticon or invisible inspection principal, which has not only dictated the design of the cell blocks, but also the prison yards and the perimeter wall and its ring of defensible bastions. The design is also particularly interesting because of the treatment of the internal spaces.

Elevations
The architectural style.

North Elevation

Fig 5. North Elevation. This version of the design includes rusticated stonework around the principal level of the building. The site slopes North to South. On this side there is a level of accommodation below that shown and on the South side two levels. The rustication is only one storey deep, presumably because it would have been too expensive to extend it to the lowest level of the building.

South Elevation

Fig 6. South Elevation. The line where the building is cut off along its bottom edge in this drawing actually marks the top of the perimeter wall of the prison. On this side of the building, there are another two floor levels extending below what is visible . The cylindrical cellblock would have been an imposing monumental structure balanced by the side wings.

Sections and Internal Elevations -

The three sections below reveal a great deal about the character that Adam intended for the internal spaces.

West-East Section looking North

Fig 7. East West Section looking North. This section shows the elevation of the internal spaces. The Inspection lodge is show with several different options for the design of the windows for the Inspection Lodge.

East-West Section looking South

Fig 8. East West Section looking South. The design of the internal elevation of the light well for the Inspection lodge is extraordinary. The lowest level is treated as an arcade, while the upper three galleries, giving access to the cells, have Doric columns and entablature..

external wall and pallisade

Fig 9. North south Section looking East. This section has elements from three different designs. The gate house and Governors House on the North side belong to CSv4, the sentry posts on the perimeter walk to CSv2

Internal Annular Well.

Adam from the school of "polite architecture". Use of orders and a classical language. For this design he appears to have worked as closely as possible with Benthams borrowed ideas from Bentham, whos utilitatrian concepts are really precursors of the modern age. Form follows function early nineteenth century.

Fig * show this balancing of two worlds. On the one side polite ordered architecture, linked to the romantic derived from classical architecture adapted to a particular purpose, and on the right an immensely modern design that prefigures the stripped down, form follows function modernism of the 20th Century. The kind of design that any modern arhitect would recognise.

The extraordingary thing about this building is that the two are in balance.

Each prisoner was given a cell in this Opera House of Correction, along with their own box with an excellent view of the stage area, in this case the pulpit from which moral corrction was tombe derived.

Inside the Bridewell

Internal view with wide angle lens

Fig 10. Internal "wide-angle lens" view. This fish-eye lens perspective view gives a sense of the enclosure and of the tension created across the space bounded by the curved bank of cells on one side and the inspection lodge opposite.The space is reminiscent of the nightmarish scenes created by the artist Piranesi in his "Carceri" or prison series of drawings. It is very likely that these drawings would have been in Adam's mind while he wa designing this building.

view looking North East

Fig 11 View of The Inspection lodge. It is not clear from the drawings what materials Adam was thinking of for the interior of this space. It is possible that the internal walls were intended to be limewash on render or a similar surface that would have helped to lighten what is otherwise quite a dark interior.

view looking South East

Fig 12. View by the Inspection Lodge South East. On the left is the Inspection Lodge with its deep recessed splayed window openings. Curving steps lead around the face of the Inspection Lodge, up to a pulpit, below which is a reading desk. The pews are for visitors, not prisoners. Each prisoner has their own balcony behind the railings between the columns on the cell galleries beyond

View looking South West

Fig 13.View from the East side looking West. This gives a sense of the brooding atmosphere that Adam has created with this design The prisoners were always behind bars on their side of these railings, overlooking the courtyard. They could be kept under permanent supervision from the Inspection Lodge, but because the rooms inside the Lodge were in darkness they would never know if they were being watched.

view from gallery to NW

Fig 14. View from the Forth Floor gallery. Outside each cell is a bay between the Doric Columns where each prisoner had a balcony with a fixed stone bench. This is the view a prisoner have had from this bench. The arched openings opposite provide light to the circulation spaces behind, which contain the main corridor and stairs between each of the floors of cells.

Upper Inspection Lodge

Fig. 15View towards upper part of Inspection Lodge.This view shows the top two levels of the Inspection Lodge.The floors of the Inspection Lodge are set half a level below the floors of the cells. In this way each level of cells could be kept under under surveillance from two levels of the Inspection Lodge.

Prisoners balcony

Fig. 16View towards Prisoners Balcony. The curved gallery giving access to each of the cells is in the foreground. Between each pair of columns is a raised bench that was intended for a single prisoner. It was from here that they would have been required to sit to listen to Bible readings and (no doubt) stern sermons exhorting them to reform their ways.

View from inside a celll

Fig. 17 From inside a cell. This view shows how each cell is overlooked by two levels of the Inspection Lodge. The intention in the design of this building was that there would be as few opportunities as possible for a prisoner to be out of sight of the guards. Inside each cell, on either side of the entrance, the wall curves so as not to provide a corner in the room in which a prisoner might remain concealed from an observer in the Inspection Lodge opposite.

view along a gallery

Fig. 18 Access Gallery. Cells open off curved galleries at each floor level. There are no doors to cells. At every opening to a cell is a corresponding balcony overlooking the central light well and itself overlooked by the Inspection lodges. The balcony space may have been intended to act as a working space for prisoners during normal days. On Sundays it was the place from which the prisoners would hear the Sunday service.

Cell galleries

Fig. 19 Access Galleries. Doric is a "male" architectural order, associated with authority and power. Including these columns and entablature puts the stamp of the authority and power of the state on this building. The railings running between the columns, give the cells the appearance of a stack of cages to hold wild animals..as if for some gladitorial contest.

Perimeter Wall, Entrance Gates and Exercise Yards
While the internal planning of the buildings is very carefully worked out., it is not immediately appearent why the curious eight sided plan shape of the perimeter walls was chosen. We can be fairly sure that the site for the Bridewell was know by the time this design was carried out, because the design depends on a sustantial fall across the site from North to South. Prisoners admitted to the prison would have been escorted down a staircase under the stairs that lead to the entrance of the Governor's House off the entrance courtyard. The level that they arrived at is the principal level of the cells. The fall across the site was therefore required for the building plan arrangement to function. This fall in level, which can be seen on the North South Section Fig 9 below, is also apparent in the Castle Style Scheme 2 design and in Classical Scheme 2.
The site actually is on an escarpment looking south over the valley between Calton Hill and the ridge of the Canongate and the Old Town to the South. The irregularity of the south edge of the site would never have allowed such a regular plan shape as Adam devised. It seems that he was really playing with "ideal" arrangements with all of the extant plans. The actual shape of the south edge of the prison wall as built can be seen in the 1897 map reproduced in the Bridewell - As Built essay.
