Concarneau is a commune in the Finistère department of Brittany in north-western France. Concarneau is bordered to the west by the Baie de La Forêt.
The town has two distinct areas: the modern town on the mainland and the medieval Ville Close, a walled town on a long island in the centre of the harbour. Historically, the old town was a centre of shipbuilding. The Ville Close is now devoted to tourism with many restaurants and shops aimed at tourists. However restraint has been shown in resisting the worst excesses of souvenir shops. Also in the Ville Close is the fishing museum. The Ville Close is connected to the town by a drawbridge and at the other end a ferry to the village of Lanriec on the other side of the harbour.
