Fans of built heritage fall immediately under the spell of the tiny village of Château-Guillaume, which nestles in the heart of the small and peaceful Allemette valley near Lignac.
The medieval castle, the former fortress of Duke William X of Aquitaine, Eleanor of Aquitaine's father, is a fine example of defensive architecture with a Romanesque machicolated keep, four towers and ramparts.
Nearby, the small Romanesque church and picturesque houses of Château-Guillaume add to the village's overall charm.
