In the heart of the Luberon, the castle of Lacoste was partly destroyed during the French Revolution but its ruins have entered into posterity thanks to 2 of its owners: the scandalous writer the Marquis de Sade and the world famous fashion designer Pierre Cardin. Classified as a historical monument, the building built on a hillside and majestically overlooking the Calavon River takes its name from this charming village in the Vaucluse region, which you should also discover.
