Ischia

Ischia is a volcanic island in the Gulf of Naples, Italy. It's known for its mineral-rich thermal waters. Hot springs bubble up at Maronti Beach, in the south. East, Roman remains lie beneath the sea floor at Cartaromana Beach. The beach has views of medieval Aragonese Castle, linked to Ischia by a stone bridge. Nearby, 18th-century Palazzo dell'Orologio houses the Sea Museum, devoted to Ischia's fishing tradition.
