Claude Nicolas Ledoux is not only the famous French utopian architect from the 18th century. He had also some very modern ideas about industrial production, urban planning, and “territorial intelligence”. The project of the royal salt works (1775-79) was an opportunity to apply several very innovating ideas about economical organisation and social living. After the French Revolution, Ledoux planned an “ideal city” which continues to fascinate by its revolutionary vision of the future.
Ledoux, Arc-et-Senans, architecture, utopia.
Warning: this text is the developed and enlarged transcription of the conference-visit at the Royal Salt works in Arc-et-Senans, provided by the author during the sixth annual conference on Territorial Intelligence, held in Besancon (France), from 15th to 18th October 2008, on the theme “Tools and methods of Territorial Intelligence”.
When we talk about Claude Nicolas Ledoux’ work, we are either tempted to reduce it to a utopialiterarily a dismissal- either to reveal its concentration universe, whether we refer to the panoptic plan of the Royal Salt works or to the Paris barriers. But his work involves many other things as well, from Ledoux’ first accomplishments as an architect, in the 1760s, to its treaty of architecture, published in 1804.
This prominent architect from the Age of Enlightenment, sometimes called “cursed” 1, has generally been neglected or even forgotten until his rediscovery, first in the United States and in Japan, afterwards in France, mainly since the 80s. The king’s architect, even if converted to the Republic, Ledoux will however meet the prison. Most of his buildings will be demolished during the 19th century, because they fitted very little the current romantic tastes. His treaty of architecture, never entirely published, has ruined him and has not found too many readers, so neither his sentences nor even the shape of his writing will be decrypted.

See also the television film Dom Juan by Marcel Bluwal (1965), with Michel Piccoli and Claude Brasseur.
Breaking off with the baroque that preceded him, Ledoux has invented an architectural writing without any concession, whose modernism will only be acknowledged in the 20th century firstly by Emil Kaufmann2, who designates him the father of modern architecture. Ledoux would therefore be the predecessor of Le Corbusier, who happened to be born on the other side of Jura Mountains. Categorized by Michel Foucault among the totalitarians, he will however be little by little recognized by the most of
the architecture theorists and two hundred years after the French Revolution the revolutionary architects:
Ledoux, Lequeu and Boullée are put in the spotlight.
Despite all that, Ledoux’ work has kept some ambiguities. The difficulty comes in the first place out of the character himself, because the man had a restless public life. A cunning young man with the women from the court, who launched him in a dazzling career, this ambitious man who became “the King’s architect” got revolutionary in order to uselessly try to escape prison. From that moment on, he dedicated himself to his masterpiece, a literary-philosophical text and a set of engravings of his art, whose depth and inspiration will have contributed to the thickness of the mystery shrouding his author. It is true that few readers will have got the chance to read this arduous text, less often reedited than the actual graphics of the treaty of Architecture considérée sous le rapport de l'art, des moeurs et de la legislation, (Architecture considered in relation to art, morals and legislation) 3.
But Ledoux’s modernism is found in his relationship with the world as well as with what was not yet known in the 17th century as the economy. The conference on the “territorial intelligence” organized at the University of Besancon in October 2008 is an opportunity to remind to what extent Ledoux was also a visionary in his approach to economy, to its territory, to the interpersonal relations and to people’s relations with this territory.
I. Ledoux and the territory In times when the physiocrats dominate on a large scale the French economical thinking, Ledoux starts in his own way an “industrial revolution” before the one of the steam engine, by suggesting settling a new salt manufacture in Arc-et-Senans. Indeed, these two agricultural villages do not dispose of any salt resource and they are situated at about 20 km away from Salins-les-Bains, where the salt exploitation began in the Roman’s time. A subterranean factory, under some impressive stone vaults, extracts the valuable salt, following an industrial procedure set up back in the Middle Age.
In this Piranesian (Fig. 1) scenery that Ledoux compares to hell, liquid brine is pumped before having it boiled in giant pans from which the workers get the salt which is then dried on the fireplace and afterwards sent across all the eastern part of the kingdom. At the foot of the Jura Mountain, in this narrow water-soak of the river pertinently called “Furious”, the steams make the work even more difficult and the wood exploitation for the households gets more and more troublesome. Ledoux, recently promoted as “inspector of salt works” considers that these systems are dangerous and uncoordinated. The architect, in a hygienist way that foresees Pasteur’s century, decides to propose to the king to build up a new wellventilated factory. To this end, he chooses an open and windy space, a virgin field like a white sheet of paper where the imagination of an architect could be freely expressed.
Above all, he uses a land settlement idea which is totally innovative: he will locate his site not next to the salted water springs, but next to the fuel, the wood. Or, Arc-et-Senans is situated on the side of one of the largest timberlands of the region, the Chaux massif; it would therefore be easier to get the brine down in water pipes following the river’s course: “It was easier to control the water flow than to transport a whole forest” writes the architect (Vidler, 1987).
This idea of settlement right next to the main production factor is really astonishing, especially because Ledoux does exactly as it would be done in an industrial area nowadays: he chooses a flat, empty and clear field, where he will be able to let his imagination free.
Without realizing it, Claude-Nicolas Ledoux has taken the salt production out of the primary sector, which in economy corresponds to extractions from nature and introduced it in the secondary sector, that Emil Kaufmann (1891-1953) art historian of the Vienna school, refugee afterwards in the USA, see bibliography.

of the industrial production, in an age where some of the economists still doubt that any other source of richness besides the nature itself could exist.

Besides, Ledoux marks the border between rough nature and the emerging industrial civilization through the wonderful entrance building and its cave, in Italian style which symbolizes the transition from the “natural condition” to that of a “city”. Moreover, the entire entrance building functions as a transition ritual. Ledoux wanted the Doric columns with no base to give the impression, when seen from the road, that the Salt works emerge from the ground… Then again, through the cave, one can catch a glimpse of the imposing house of the manager (Fig. 2), whose colonnade is also designed to be visible from a distance.
In this way, the entrance in the Salt works looks like a gate to another world wanted perfect by Ledoux.
This cosmic idea is to be found in a restrained shape in the cemetery of the city of Chaux which Ledoux imagined for his ideal city. In this utopian cemetery, the relation with death is a purely poetic one, since the centre of the whole cemetery is an immense round empty room, symbolizing the absolute void.
This room has only one zenithal circular gap, which allows imitating by reflection the Sun’s itinerary on the walls of the sphere. On the outside, the cemetery is invisible, being built underground and having only one semicircle emerging similarly to a floating planet in the clouds: it is under this allegorical shape that Ledoux actually presents his work in an engraving of his treaty of architecture (Ledoux, 1804, plate 100).
The fact is that the two successive plans which he shows to the king for the Salt works are the result of an unlimited vision, where the shape is not explained by the morphological constraints of the territory, but only by the function.
The two projects are alike in terms of their care to organize the industrial functions, to enable the flow, while guaranteeing hygiene and safety. The buildings are ventilated and spacious in order to prevent fires and to protect health; even vegetable gardens for the workers are calculated.
In the 2nd project, created starting with 1775, Ledoux provides an almost promethean vision of the industrial age which is supposed to bring about wealth and harmony. In this way, he opposes to the pure
and uncontrolled nature a universe (out of which he will make an ideal city later on), where each thing has its own place, in harmony with the outer space.

This harmony lies firstly in the air and the sun. The cosmic vision is provided by the shape of the Salt works, which looks like a sundial. The shape must be “pure as the one of the Sun during its journey” says the architect. But the radiant organization allows also the functional distribution, each building trade owning a building and an equal part of the sun and of the public and private space (especially the gardens).
The obsession for meaning characterizing Ledoux’ work determines him to explain even that the building situated at the most western point will be appointed to the clerk who will be the last ones to work every day, writing down in the books the daily production… At midday, the Sun is of course at its height on the top of the director’s house, which also stands for the justice palace and the church… In one of Ledoux’ engravings we can even see the sun crossing over the building and illuminating the priest, who is on the top of the stairs, where everything converges.
We obviously think of Tommaso Campanella’s Cité du Soleil (City of the Sun) (Campanella, 1972)… The feeling that the Royal Salt works have a secret connection with the outer space is still present nowadays: the strength and the balance which come out of this architectural composition determine a feeling in between trouble and fullness: there are some who leave it serene, there are others who leave it panicked. Conductor Emmanuel Krivine, who would spend many summers at the Royal Salt works with the French Youth Orchestra, used to say that inside the salt works one has to face oneself… Those who have spent some time there know at what extent this could be a good or a bad experience…
II. The architect’s eye The second compositional element is the reference which Ledoux explicitly makes to the ancient theatre. In the opinion of Anthony Vidler (1987, p. 49)4, “we literarily have to interpret the Salt works as a theatre, since it follows the lines of the ancient amphitheatre as described by Vitruve and illustrated by Perrault” (in the work published in 1673, that Ledoux thoroughly examined).
Just like the theatre of Besançon, whose revolutionary auditorium breaks with the Italian model of theatre and becomes the prototype of the “modern” auditorium, the shape of the Salt works represents the social and political ideal of the City of Chaux.
We can also call theatrical in the Salt works the combination of
elements and dramatic motifs, whether we refer to the colonnade of the director’s house, which has to play with the sun, or to the salt urns, or to the imitating rustic roofing. It is the “talking architecture”, with its production and strength symbolism.
