A stronghold build c. 1300 on a hilltop by the Grimaldis of Cagnes, transformed into a palatial home c. 1620 (reception rooms and staterooms in the Baroque style, splendid trompe-l'oeil paintings). Today, it features several collections : ethnographic museum of the olive tree, Solidor Donation, museum of modern Mediterranean art. Worth seeing in summer : the International Art Festival.
