Roadstead of Brest

The roadstead of Brest is a roadstead or bay located in the Finistère department in Brittany in northwestern France. The surface area is about 180 km². The port of Brest and one of the two French naval bases, Brest Arsenal, are located on its northern edge. It is linked to the Atlantic Ocean by the Goulet de Brest, a strait about 1.8 km wide. Three main rivers drain into the roadstead: the Penfeld, the Élorn and the Aulne.
