The Fort de la Fraternité (fort of brotherhood) 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 (around a gun battery built in 1695) as part of the defences around the goulet de Brest.
