Paestum was a major ancient Greek city on the coast of the Tyrrhenian Sea in Magna Graecia. After its foundation by Greek colonists under the name of Poseidonia (Ancient Greek: Ποσειδωνία) it was eventually conquered by the Lucanians and later the Romans. The Lucanians renamed it to Paistos and the Romans gave the city its current name. The ruins of Paestum are notable for their three ancient Greek temples which are in a very good state of preservation. Today the remains of the city are found in the modern frazione of the same name, which is part of the comune of Capaccio in the Province of Salerno, Campania, Italy.
