The Château de Crussol is a mostly-ruined 13th century limestone castle in the commune of Saint-Péray that dominates the valley of Rhône, just opposite Valence in Ardèche.
Located over the peak of the hill of Crussol, at the edge of a cliff over 200 metres above surrounding plain, the castle overlooks Saint-Péray in the west, and Guilherand-Granges and Valence in the east. The site comprises about 3 hectares, including the Vilette, a small hamlet of about a hundred houses, and the castle itself at the top of the hill. The entire grounds are enclosed by ramparts that are still quite visible.
The hill of Crussol has been occupied since Roman times. Initially, it was the site of a temple, which was subsequently extended with a fortified building to the south in the course of the 5th century, but was abandoned in later centuries for the present site.
