Maison des Seigneurs

Highlight • Historical Site

This fortified house, visible from afar, was part of a complex that was intended to protect the port of Le Conquet from raids, which had been very frequent since the 13th century, and to facilitate the collection of shipping fees.
The complex consisted of three watchtowers staggered along the southern bank of the Ria. Remains of one of these buildings still remain and another has been converted into a residential building. They were older than the Poncelin House (or Maison de Seigneurs), which can be dated to around 1510.

Fort de l'Îlette

It is possible to access the fort at low tide, from where you will have a superb view of Blancs Sablons beach and the Kermorvan lighthouse. Watch out for the rising tide and slippery algae-covered rocks.

Built by Vauban in the 17th century on a rocky islet to monitor the port of Brest. Its geographical position allows it to always have an eye on the entrance to the Goulet de Brest, an arm of the sea which connects the harbor of Brest to the Atlantic Ocean. Today the fort is accessible by a footbridge and can be visited in summer. For many centuries, the harbor of Brest attracted the desires of invaders. Since the Middle Ages, protection posts have been set up on the coasts to control its entry. The most effective of them: Bertheaume, a rocky islet located thirty meters from the shore, in Plougonvelin. In the 17th century, around 1690, at the request of Louis XIV, Vauban built a formidable fort there, which would be used militarily until 1944.
