We drove up the hill, where we could see the ruins of the Chateau de Calmont D`Olt (castle of the 11th century). The grounds were closed to the public as were arrived there off season, but we did have a marvelous view of Espallion from there. We couldn`t see the castle grounds well, since it is surrounded by a high wooden fence, and also because parts of the castle were covered with tarps, probably for renovations. The dirt winding road was surrounded by a few abandoned small houses, seemingly from the same age as the castle itself, and everywhere we found chesnut trees.
In the tourist season, they do have children's activities and historical observation organised. Also, for the adults, they have archaeological sites and tours, which should take one even down to the 14th-century dungeons.
