The Sunken City of Baia, Italy. It was a Roman seaside resort on the Bay of Naples.Baiae was even more popular than Pompeii, Herculaneum, and Capri. Baiae was sacked by Muslim raiders in the 8th century AD and was deserted because of malaria by 1500. Because of coastal subsidence most of Baiae is now under water in the Bay of Naples, largely due to local volcanic activity.
