Ouvrage Cap Martin, Military museum and bunker in Roquebrune-Cap-Martin, France
Ouvrage Cap Martin is a Maginot Line fort on the eastern slope of Cap Martin in Roquebrune-Cap-Martin, at about 27 metres altitude. Three surface blocks, mostly north-south, hold steel cloches and embrasures for guns and mortars; a rusted metal dome with a small top fitting sits in a low concrete ring on the grassy slope. Below, galleries dug at least 12 metres under rock link the barracks, filter room, telephone exchange, kitchens and magazines.
This fortress was built in the early 1930s as part of a French defensive network along the Italian border. It saw combat when Italy entered the war and attacked the Riviera coast.
This fortification served as a critical defensive post for the French Riviera and its spaces still reflect the presence of those who worked here. Visitors can walk through rooms where soldiers lived and worked, gaining a direct sense of their daily routines in this underground world.
The ouvrage lies on the eastern slope of Cap Martin in Roquebrune-Cap-Martin, about 27 metres up, with the crest reaching 74 metres just to the south-southwest. The main ouvrage and the Pont Saint Louis casemate are open to visitors during the summer months, the casemate since 1995 and the ouvrage since February 2008. Access runs through the entrance block and down to the gallery below, reached by steps and hoists.
The fort's underground gallery lies some distance below the entrance and combat blocks, reached by steps and hoists, and was served by a 60 cm narrow-gauge railway whose wagons were pushed by hand and built to a design found nowhere else in the Alpine Line. This layout, with a deep circulation gallery, is more typical of the main Maginot Line in northeastern France.
