A small detour through the ruins (very discreet) of the castle of Foirevielle offers a beautiful view on La Chapelle-en-Vercors and the surrounding valleys. In the ninth century, this caste motte watched the roads coming from Vassieux or the col de Rousset. The village of Bâtie de l'Orme and then of the Bâtie de Vercors huddled at his feet. It was in the twelfth century that the villagers moved the village to the present location.
