The remains of the castle: from the castle there remains a substantial wall and a few constructions that one would not suspect from the village. It is reached by a pleasant little hike starting from the Carol's church. Follow the signs and yellow markings. Allow 1h30 round trip. In the village, follow the signs to the castle. The path leads first to the church located high up away from the village. Go around the adjoining cemetery on the right to enter the path. During the small climb through the woods, we notice the arrangement of old terraces and large stone walls supporting the path. Arrived on the ridge we discover the remains of the castle of Teyrac also called Castellas de Roquefort. It belonged to the lords of Lévis-Mirepoix. Beautiful view overlooking Roquefort-les Cascades and its valley. Continue on this path which leads to the pylon. You get there by walking along the cliffs frequented by climbing schools. From the pylon we discover Castella-de Roquefort on the other side of the Plantaurel and a beautiful panoramic view of the country of Olmes.
