Fodor's Choice
This stunning underground fortress displays archaeological relics from 2,600 years of settlement here. In the mid-1990s, archaeologists discovered traces of an Iron Age settlement from the 6th century BC underneath the town's castle. Structures are believed to have existed here from Roman times, with later castles being built one on top of another through Moorish and medieval times. The current castle and adjacent church are from the 13th century.
