One of the best-preserved Greek temples is in Italy at Paestum, just south of Naples and Sorrento. Founded as the city of Poseidon in the sixth century B.C., this was a key stop on an important trade route. The Romans conquered and took it over in the third century B.C., changing its name to Paestum. Malaria-carrying mosquitoes kept the location desolate for almost 1,000 years. Paestum was rediscovered in the eighteenth century. Today, it offers travelers to Europe several impressive Greek ruins to visit.
