Origin and history

The former factory of the Chemical Society of Clamecy, today the Solvay factory, is established as an emblematic industrial ensemble of the twentieth century. Located on the left bank of the canal, it was served by a parallel railway and consisted of production units, an administrative prefabricated concrete building (Art Deco style), a social centre, a railway station and a stadium. At its peak, the factory employed up to 600 workers and formed a real "city in the city", with workers' towns, chapel and utilities. Its historical activity, the carbonization of wood and coal, ceased in 1981 to give way to petrochemistry.

Founded in 1894 by the Société Barillot, Houdé and Cie, the factory became in 1922 the Chemical Society of Clamecy. Under the direction of Maurice Brulfer (1919–66), she experienced an exceptional expansion. In 1937, architect René Allard erected an Art Deco administrative building adorned with a frieze painted by Neveu-Lemaire, extended in 1951 by Rex Barrat. An adjacent social centre, decorated by Robert Pouyaud, completed this modern ensemble. The murals, still visible, bear witness to this lavish era, when industry shaped the social and urban landscape of Clamecy.

The site is part of a local industrial history dating back to the 19th century, when the decline in wood flotation freed land along the canal. As early as 1851, a steam sawmill was installed, followed by factories at tan and activities related to founders such as Jules Galuzot (Spring stores). The chemical factory, with its extensions of the 1950s, symbolizes this transition to a structured industrial economy. Partially listed at the Historical Monuments in 2014, it illustrates the technical and artistic heritage of the French industrial heritage.
