With a thousand castles and almost as many churches, France’s south-western Périgord region is a paradise for lovers of ancient stones. Aude, 32, has inherited the fortress of Commarque. The young Parisian left everything behind to protect this 12th-century monument. Gastronomy is also a key part of life in the Périgord. In this region that cherishes quality produce, chef Pierre Corre cooks black truffles like no one else.
