A naturalist's full-scale laboratory.
When he had his Grande Forge built in 1768, Buffon was already past sixty. Author of the monumental Histoire naturelle and intendant of the Jardin du Roi in Paris, he was one of the most widely read scholars of his century. On his estates at Montbard, he wanted to test some of his theories first-hand: measuring heat and the cooling of metals, estimating the age of the Earth from iron spheres heated red-hot. The forge became his full-scale laboratory.
Built between 1768 and 1772, it ranks among the first integrated factories in Europe: blast furnace, finery forge, slitting mill, master's house, workers' cottages, chapel and bakery all arranged around a vast rectangular courtyard. By the end of the century, close to 400 workers were producing 450 tonnes of iron a year. Here were forged the railings of the Jardin des Plantes, naval parts and tools. After 1866, the site converted to cement, before falling silent in 1923. Listed as a Historic Monument in 1943 and again in 1985, it retains today an overall coherence that is rare in France.
An intact factory-château.
The visitor first discovers the austere façade of the blast furnace, then the famous monumental staircase by which Buffon invited his distinguished guests to watch, from a gallery, the pouring of molten iron — a spectacle at once scientific and aristocratic.
Then come the forge halls, the water channels, the master's pavilion with its listed drawing room and dining room, the terraced gardens and the preserved workers' village.
Buffon was neither an industrialist dabbling in science nor a scholar making a foray into industry: he was both in a single breath. The Forge tells the story of this singular figure, the naturalist-industrialist, where the curve of a cooling metal converses with the history of living things.
The gates of the courtyard of honour.
The wrought-iron gates that close the courtyard of honour were forged on site, in 1768, by Buffon's own workers — the first gesture of a manufactory announcing its arrival in the world.
For a stay at Maison Jazey, it is the perfect counterpoint to the abbeys and the vineyards: a page of the Auxois where the Enlightenment becomes matter.
