Pointe de Corsen, Westernmost headland in Plouarzel, France

Pointe de Corsen is a 30-metre granite cliff at the western end of Plouarzel in Finistère, the westernmost point of continental France. The cliff face is cut by fissures and shows large panels of gneiss enclosed in the granite, visible at the point itself. A small sandy cove and flat rock shelves lie at its base, with boulders scattered across the low green slope above.

The CROSS Corsen maritime rescue centre opened here in October 1982, after the Amoco Cadiz ran aground in March 1978 and no such centre existed near Ouessant. The headland marks the theoretical boundary between the English Channel and the Atlantic, and the Corsen lighthouse stands beside ruined buildings of the old lighthouse and beacon service depot.

The name comes from the Breton Beg Korzenn, "point of the narrow channel", referring to the Chenal du Four offshore. Locals also call it Beg ar Chach, "point of the dogs", while in Le Conquet it is Beg Paol, after Saint Paul. The CROSS Corsen station on the road to the point opens to the public during the European Heritage Days and for groups such as schools and maritime associations.

The CROSS Corsen centre stands on the road to the point, and the phare de Corsen with its ruined outbuildings lies close by; the phare de Trézien stands 1.5 km inland. The CROSS opens to the public during the European Heritage Days and, on request, for school groups and maritime associations.

The CROSS Corsen centre opened in October 1982 at the request of the Ministry of the Sea, after the Amoco Cadiz ran aground in March 1978 and no such centre existed near Ouessant. It coordinates surveillance of the Ouessant shipping lane and sea rescue between Mont Saint-Michel and the Pointe de Penmarch. It opens to the public during European Heritage Days and to groups on request.
