Crotone is a port city in Calabria, southern Italy. The monumental Castello di Carlo V is a 9th-century fortress that was modified in the 1500s. The National Archaeological Museum houses items, including a gold tiara, unearthed at the ancient Temple of Hera Lacinia in the nearby Capo Colonna Archaeological Park. Farther south is the Capo Rizzuto Marine Protected Area, with seagrass forests, barracudas and starfish.
