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 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. As
Pesto or
Paestum, the medieval town became a
bishopric, which is now a Latin Catholic
titular see
