The Luberon is rich in Roman history. A major Roman road from the Italian peninsula to Spain ran along the north side of the Luberon, passing through the Roman town of Apt (Colonia Apta Julia) and crossing the Calavon on the Pont Julien, which still spans the river today. There is an elaborately ornamented Roman arch in Cavaillon, as well as a museum with important Gallo Roman artifacts. In a museum in Cucuron you can see bits of sculpture and a remarkable incised fresco recovered from the remains of a Roman villa discovered by a local farmer as in 1983. Most impressive of all are the ruins at the Fort de Buoux, a Protestant stronghold near the headwaters of the Aigue Brun that survived the Wars of Religion only to be taken and pulled down by Cardinal Richelieu in the 17th Century.
