Fort de la Fraternité


The Fort de la Fraternité is a fort located on the îlot du Diable in Roscanvel, France. The whole complex is now in ruins, though a gunpowder magazine is still standing, with a roof of large rectangular tiles and elaborate guttering.
The fort was built in 1791 as part of the defences around the goulet de Brest. It was modified in the second half of the 19th century, though it was abandoned by the military in 1870 and turned into a storehouse for wood and lime.
A casemate was added by the Germans in 1942.
