Former gasworks

The plant, built in 1842 to produce gas from coal, was modified several times, completely rebuilt in the 1920s and 1930s, and remained in operation until the 1960s. It had three gasometers (10,000 m³), which were destroyed in the 1980s. Around 1965, the furnaces and installations were replaced by offices and technical workshops.

Located on the banks of the Meuse on a 17,500 m² site crossed by the Charleville-Hirson railway line, the 1920s-30s buildings are made of reinforced concrete and brick, with shed roofs or Caquot vaults. The spare parts shops have reinforced concrete vaults supported by an exposed framework. The laboratory, converted into offices, dates from the 1960s.

To the west, the workers' accommodation consists of two limestone houses (with mechanical tile roofs); to the east, other rubble stone dwellings have slate roofs.
