Hôtel d’Agar
Part museum, part cabinet of curiosities, this 14th-century mansion in the heart of Cavaillon, a medieval town 15 km (9 miles) west of Ménerbes, is an extraordinary repository. Its five floors contain architectural and archaeological artifacts (some found in an on-site dig), religious relics, ancient books and prints, tapestries, and musical instruments. In addition, a remarkable collection of art includes everything from masterpieces by Caravaggio and Artemesia Gentileschi to modern works by Victor Vasarely and Cy Twombly—each illustrating, in its own unique way, the story of this fascinating region. Even the garden is a wonder, harboring the remains of Hellenistic and Roman temples. Visits, by reservation only, can be made on the website.
