Sillans-la-Cascade was a village with three castles: the first one, a medieval castle, ruined in the late Middle Ages. The second one, built in 1609 in the surrounding area, was destroyed during the Revolution. The third one, built in the early 19th century by Rolland Sillans in the middle of a park, was bought by the town in 1992 to the Count François de Castellane.
