Architecture
The castle, also known as the Saint-Clair Tower, is an ancient fortified castle, the remains of which stand in the woods, 2.5 kilometers north-northeast of the town. The building was first partially registered as a historic monument by decree of July 16, 1925 by the French Ministry of Culture, to protect the Saint-Clair tower. In November 2021, protection was extended to the entire site, both built and unbuilt parts, in order to protect the surrounding area, the moats and the buried remains.[5]
