Housed in one wing of a 17th-century former Benedictine convent, this is predominantly a modern art gallery. It puts on temporary exhibitions, but in its permanent collection are a number of paintings and collages by Gaston Chaissac who belied his working class roots to become a celebrated early 20th century painter for his often colourful, simplistic works, as well as sometime sexually explicit paintings by Surrealist Victor Brauner. In the attic of the museum is an interesting collection themed around the sea and the life of those connected to it, including model ships, local costumes and everyday objects.
