Driving from St. Remy to Nice on backroads we passed through the small, beautiful hilltop town of Gordes. It was the site of a major castle in medieval times, and one that still stands today having been rebuilt during the Renaissance. Beneath the town are seven levels of caves that housed an olive oil mill, tannery, cobbler, cisterns, silos, and a chapel. We were told that the underground industry was necessary because of a lack of space with the walled fortress above.
