About three kilometers north of the town center is the Domaine de Boisbuchet with the Château de Boisbuchet, built in 1865 on a hill above the Vienne. The castle and the approximately 150 hectare estate were bought in 1989 by the German art collector Alexander von Vegesack, curator and director of the Vitra Design Museum in Weil am Rhein, to use it during the summer months for workshops for artists, designers, architects and students.
