At the top of the hill that dominates the Vaucluse village of Séguret stands the imposing western facade of the keep of the feudal castle built in the 10th century. Visitors can also observe several sections of the walls which joined, on the north side, the Portail de la Bise and, on the south side, the Portail Neuf giving access to the village. A steep path climbs between the rocks above the Saint-Denis church and leads to the remains of Séguret's castle.
