French Revolutionary Architecture

Visionary Architecture between Enlightenment and Revolution

These seven motifs bring together drawings by Jean-Jacques Lequeu, Claude-Nicolas Ledoux and Étienne-Louis Boullée. Their work is frequently grouped under the term French Revolutionary architecture, although some of it predates 1789. They share a confidence in geometry, precise draughtsmanship and an architecture whose form was intended to express its meaning directly. The selection ranges from a built industrial complex to radical monuments that remained entirely on paper.

AP 516 · Jean-Jacques Lequeu, Instruments du Dessinateur, 1782

Trained as a technical draughtsman, Lequeu made drawing itself the subject of this richly annotated sheet. Rulers, set squares, compasses and aids to perspective appear beside an eye, an ear and the hand at work. The composition thus combines instruction in tools with close observation and manual practice. Watercoloured details, shadows and shifts of scale turn the teaching sheet into a portrait of the draughtsman as well: architecture begins here not with construction, but with seeing, measuring and the controlled line.

AP 406 · Claude-Nicolas Ledoux, Réalisations et projets

This survey arranges Ledoux’s buildings and unrealised designs in a dense grid of plans, elevations and perspectives. It reveals the exceptional breadth of his work, from houses and utilitarian structures to gates, theatres and visionary institutions for the ideal city of Chaux. Recurring primary forms – circle, square, cylinder and pyramid – turn a building’s function into a legible image. The juxtaposition makes clear that Ledoux was designing not only individual structures but a society ordered through architecture.

AP 705 · Claude-Nicolas Ledoux, Maison du Directeur

The Director’s House occupies the centre of the semicircular Royal Saltworks at Arc-et-Senans and forms both its spatial and hierarchical focus. The whole production complex could be surveyed from this point. Ledoux gave the administrative building the dignity of a temple: a powerful portico supports a triangular pediment, while the tall roof and circular window emphasise the central axis. Columns built from alternating cylindrical and squared stone courses are especially distinctive. AP 705 isolates the principal façade, making its rigorous symmetry immediately apparent.

AP 514 · Étienne-Louis Boullée, Cénotaphe à Newton, 1784

Boullée’s unbuilt cenotaph honours Isaac Newton with a monumental sphere – a form without a privileged viewpoint that could signify both perfection and the cosmos. Terraces and rows of dark trees make a horizontal base above which the pure geometry appears like a celestial body in its own right. The design largely abandons conventional façade composition and instead employs scale, light and shadow as its expressive means. AP 514 presents the celebrated exterior view, in which the human figure and entrance almost disappear beside the immense sphere.

AP 533 · Jean-Jacques Lequeu, Il est libre, 1798/99

“Il est libre” is not one of Lequeu’s conventional architectural projects but belongs to his enigmatic figure drawings. A nude body twists through a dark round-arched opening; masks or caryatid-like heads support the architectural frame, while a small winged figure appears to fly away above the keystone. Dated to Year VII of the Revolutionary calendar, the drawing joins body, ornament and architecture in a deliberately ambiguous scene. Its title – “He is free” – invites political, personal and ironic readings without fixing any one of them.

AP 234 and AP 704 · Royal Saltworks at Arc-et-Senans

Commissioned by Louis XV and built to Ledoux’s designs between 1775 and 1779, the saltworks was among the earliest industrial complexes to be conceived with the architectural ambition of a palace. Each building in the semicircle had a clearly defined purpose; production halls, administration and housing formed a rationally organised whole. Brine arrived through a pipeline approximately 21 kilometres long from Salins-les-Bains and was evaporated with timber from the nearby forest.

AP 234 concentrates on the entrance pavilion. Its monumental colonnade encloses a grotto-like formation of stone whose rough surface evokes water, rock and the source of salt – a vivid example of Ledoux’s “architecture parlante”, or speaking architecture. AP 704 places several elevations of the complex above one another: the rhythm of low wings, porticoes and accented central buildings makes the hierarchy of the semicircle legible even in a flat panorama. The complete ideal city of Chaux that Ledoux later designed, by contrast, remained on paper.
