Origin and history

The Châtellerault arms factory, nicknamed the Manu, was created by royal ordinance on 14 July 1819 on the banks of the Vienne, in the centre-west of France. This strategic choice responded to the closure of the northern factories (Maubuge, Charleville, Klingenthal) after the Napoleonic wars, considered too vulnerable near the borders. The site benefited from a local metallurgical tradition (cutlery) and hydraulic power from the river. Originally dedicated to white weapons, production extended to firearms from 1830, then to artillery and missiles in the 20th century.

Between 1819 and 1886, the site adopted a symmetrical plan with tuffled buildings, led by architects Ledard and Guillebon. The industrial boom profoundly altered the landscape: sheds, brick hangars, and chimneys (including one of 61 m) appeared after 1886, while concrete and glass dominated from 1914. The labour force rose from 34 workers in 1819 to 8,000 during the First World War, nicknamed Manuchards. The factory produced iconic weapons such as the Chassepot rifle (1870) or the Lebel M1886, as well as artillery pieces such as the 75 mm hydraulic brake.

Closed in 1968, the Manu was converted into a cultural pole by the city of Châtellerault in the 1970s. The site now houses the Auto Moto Vélo Museum (including a space on the factory), a rink (La Forge), armament archives, a circus school, and contemporary works such as Jean-Luc Vilmouth's 2 Tours (1994). Four brick chimneys and several buildings (including administration, classified) bear witness to this industrial heritage, partially protected since 1989.

Hydraulic power played a key role: a Fourneyron turbine was installed in 1844, followed by thermal and hydroelectric power plants (1914–1921). During the Second World War, the factory employed 7,000 workers, becoming one of Europe's largest weapons factories. After 1968, archives, museums and sports facilities (skate park, sports halls) perpetuated the memory of the site, while at the same time plunging into local life.

The factory was also a geopolitical actor: it manufactured weapons for Russia before 1914, under the supervision of Grand Duke Nicolas. Its decline is part of the modernization of the French army, with the replacement of obsolete weapons such as the Chauchat gun-gun by MAC 24/29 from 1924. Today, the site combines industrial heritage, artistic creation and education, illustrating an exemplary reconversion.
