A very nice castle. There are very nice tours and a brochure in the desired language (in this case German). Photos inside are not welcome and that's fine.
The Maison forte de Reignac was built in the 16th century under a cliff (abri) and was inhabited until the 20th century. In the meantime, it has been transformed into a museum.
