Origin and history

The Hunaudière forge, located in Sion-les-Mines (Loire-Atlantique), is an industrial site dating back at least to the early seventeenth century. Originally owned by Henri de La Chapelle, Lord of Zion, it passes through inheritances and successive sales to noble families such as the Rougé or the Prince of Condé. During the Revolution, his property was confiscated as national property in 1792 and then sold to local industrialists in 1802, including François Demangeat, a smelter manager.

The site specializes in the production of cast iron (via a blast furnace) and its transformation into iron in a refinery, then into nails via a nail factory. His activity ceased in 1883. The forge retains remarkable elements such as an 18th-century refinery chimney, a Saint-Éloi chapel, and two master houses (one of which was built in 1825). It was protected in 1986–1987, with parts classified (bridges, facades, roofs) and listed as historical monuments.

In the 19th century, the forge changed hands again: the Nantes shipowner Poydras de la Lande acquired in 1852. The site illustrates the evolution of metallurgical techniques in Pays de la Loire, linked to the exploitation of local ore. Today, he mixes communal and private properties, with vestiges of his industrial past (bourbers, director's house, workers' houses).

Historical sources (Belhoste, Goudé) highlight its role in the regional economy, while the Merimée base lists its protected architectural elements. The forge embodies the industrial heritage of the Loire-Atlantique, between seigneurial heritage, technical revolution and workers' memory.
