It was within the walls of this splendid mansion that Charles Gounod played the first bars of his opera, Mireille, to the Provençal author Frédéric Mistral, who wrote the libretto. Today, in an attractive retro-style dining room with the occasional Art Deco touch, guests can sample a culinary score inspired by the region’s finest ingredients, including outdoor Provence tomatoes, Mediterranean squid and crayfish, and lamb from Crau.
