Musée de la mine de Noyant-d'Allier, Mining museum in Noyant-d'Allier, France.

The Musée de la mine de Noyant-d'Allier occupies a former colliery whose red-brick buildings are pierced by a central concrete headframe with open rectangular levels and a flat cap. A massive angled concrete beam on splayed legs extends to the right, and a yellow mine train car stands on the 600 mm Decauville track in front. Ivy climbs the facade.

Coal was mined around Noyant-d'Allier since the 18th century, when about twenty pits operated nearby. In 1920 a concrete headframe was built to Eugène Freyssinet's plans above the central shaft. Early in the 20th century a Decauville O20 T steam locomotive linked the pits and spoil heaps near the Moulins–Montluçon line. Mining ended with the mine's closure in 1943.

The museum is run by the Association des Amis du Musée de la mine, founded in 1988 and revived in 2002 on the initiative of the mayor of Noyant-d'Allier. Its trains and wagons were recovered from mining sites as they closed, and volunteers restored the Decauville line and the recreated mine. The guided tour of the carreau is led by these volunteers.

The narrow-gauge Decauville line runs 1,800 m on a 600 mm gauge and operates from May to September. The train is integrated into the museum visit and gives a guided tour of the mine yard, where the concrete headframe stands. The site lies in the Allier department, Auvergne-Rhône-Alpes, near the former Moulins–Montluçon line.

After the mines closed, former workers' homes were given to families from Southeast Asia, establishing a Vietnamese community in this French mining town. This unexpected link brings together two different cultures in one place.
