It’s a troglodyte village on the left bank of the Tarn, dominated by a ruined castle. The legend says that during the time of the Crusades, all men went to war, except the Lord of Castelbouc.
According to the legend, he had to satisfy all the village women, in need of man, and he died of exhaustion. At night, his ghost-shaped goat (names bouc in French) flies over the castle. This gave the name to the place.
