The Château de Rustéphan is a small, ruined 15th–16th-century manor-house in Nizon, part of the commune of Pont-Aven in the Finistère département of France.
[1] It was erected by Jean du Faou,[citation needed] chamberlain of France and grand seneschal of Brittany, who built the domaine in 1420.
The original manor was built by the son of a Duke of Brittany, named Étienne, Count of Penthièvre, and seigneur of Nizon, who died in 1137.
The section on the left, the gable wall, contains a corner turret on corbelling, immense hooded fireplaces as well as the remains of some stone cross-pieced windows.
[1] It is believed that the manor house once consisted of a rectangular corps de logis and had turrets at each of the corners, as well as a large central staircase tower.
