In its original form this small castle was built around 1300 by Rainier Grimaldi, the Seigneur of Cagnes and Admiral of France. During two hundred years it endures sieges and assaults. In 1620 it is transformed into a stately home combining the charm and the wealth of a palace by the Baron Jean-Henri Grimaldi : a monumental staircase, a patio boasting two levels of arcades testify to a strong italian baroque influence. Transformed into a Municipal Museum in 1946 then classified as a historical monument in 1948, it is currently a stupendous showcase for the Olive tree ethnographical Museum, the Solidor donation (including works by Picabia, Foujita, Van Dongen, Cocteau, Dufy etc.), the Mediterranean museum of modern art (including works by de Kijno, Ben, Picasso, Lurçat, Coignard, Franta, Marie Raymond, Chabaud etc.) and contemporary art exhibitions. By a narrow staircase visitors can access the tower, which offers a magnificent panoramic view of the Bay of Angels and the medieval village.
