Stade du Moustoir, Football stadium in Lorient, France

Stade du Moustoir is a sports ground in Lorient, France, serving as the home venue for FC Lorient. The stadium features a bowl-shaped design with seating surrounding the field, a carefully maintained playing surface, and has undergone several upgrades over the years, most recently with a hybrid pitch and refreshed stands.

The first sports park opened here in May 1924, inaugurated by mayor Édouard Labes, with a cement cycling ring replacing the old velodrome on place de Rohan. Damaged and requisitioned as a German munitions depot during the war, it was rebuilt about a hundred metres away and inaugurated in July 1959 in the Moustoir district, which gave the stadium its usual name. It was renamed stade Yves Allainmat in September 1993 after the former mayor and deputy, who had died a few months earlier.

Since 1971 the stadium has hosted the Festival interceltique de Lorient every summer, including the Championnat national des bagadoù, the competition of Breton bagpipe bands. The ground is owned by the municipality of Lorient, not by FC Lorient.

The stadium sits near the city centre in the Moustoir district, on the far side of rue Jean Le Coutaller from the Lycée Dupuy-de-Lôme. The ground is owned by the municipality of Lorient, and its commercial capacity is 18,100 spectators. Access is through the stands around the pitch; the cycling track that once ringed the field was removed during the work begun in 1998.

The stadium's official name since September 1993 honours Yves Allainmat, a former mayor of Lorient and deputy who died a few months earlier. The council renamed it by municipal decision, while the everyday name comes from the Moustoir district where it stands. Look for the naming on the stadium facade.
