Description: Aerial CHÂTEAU ROCHER, France Château Rocher (or Château fort de Blot-le-Rocher) is a French castle overlooking the Sioule river valley. It is located in the commune of Saint-Rémy-de-Blot in the Puy-de-Dôme département of the Auvergne région. The ruins standing on a cliff above the river, are the remains of a 13h-century construction, with evidence of earlier (11th century) building. The castle was built by the Lords of Bourbon. A masonry bridge crossing the moat comes up against the entry door, now ruined, and the outer wall. A second wall existed in front of the two eastern towers. Three principal towers flanked the east and north fronts. Privately owned, Château Rocher has been listed since 1913 as a monument historique by the French Ministry of Culture.
