Tropea is a small town on the east coast of Calabria, in southern Italy. It’s known for its clifftop historic center, beaches and prized red onions. Built on a former Byzantine cemetery, the 12th-century cathedral has marble sarcophagi and a painting of the Madonna of Romania, the town’s protector. Nearby is a viewpoint over the hills. The centuries-old Santa Maria dell’Isola Church is on a rock overlooking the sea.
