La Roche Maurice is a pleasant small town with many old houses and a splendid church. It is dominated by the ruins of Roc'h Morven Castle on a rocky promontory towering above the town.
Restoration work has been done on this and there are a series of information boards around the site. There is a well made path up to the castle and access is by an outside metal staircase.
Parts of the curtain wall can be seen. There are the remains of the kitchens with ice store and the castle keep which is roofless and has no internal structures left. The stone keep was built at the end of the 12thC and the castle was extended in the 14thC by the Rohans following a fire. There was further work in the 15thC. The castle was abandoned and the stone robbed for buildings.
The church is also worth a visit with its painted ceilings and remarkable rood screen.
