The interesting vestiges of the Château des Baux, demolished in 1632 by order of Richelieu, include the ruins of the citadel, towers, the castle chapel (12C-16C) and the keep, with a splendid panorama. You enter via a space that uses models to relate the site's glorious past. Its other points of interest are a monument dedicated to the poet Charloun Rieu and the Chapelle St Blaise. The castle plays hosts to events, most notably the Médiévales des Baux, from April to September.
