Gaeta

Gaeta is a coastal city in central Italy, south of Rome. It's home to Monte Orlando Park, a protected area with Roman ruins, Mediterranean vegetation and dive sites. Inside the park, an 11th-century sanctuary sits on Montagna Spaccata, named for a wide split in the rock that plunges into the sea. A staircase leads to the nearby Grotta del Turco marine cave. Northwest is the Villa di Tiberio archaeological site.
