The Temples of Paestum are among the most important archaeological finds from ancient Magna Graecia. The optimal structural condition of the Temples of Paestum make them among the most appreciated monuments of the Greek civilisation. The Temples are among the main attractions of the Archaeological Park of Paestum and make it one of the most important archaeological sites of Magna Graecia. The Archaeological Park of Paestum is very large and is surrounded by a still existing wall with a polygonal perimeter of almost 5 km. Inside the ancient city of Paestum, also known as Poseidonia, there is a route along which it is possible to visit some of the most important monuments of Magna Graecia. Here we find three temples, an amphitheatre, a forum with comitium, but also sanctuaries and necropolis, where one of the most famous tombs in the world, the Tomb of the Diver, was found. The name Paestum was actually given only in Roman times, the Greeks had called the city Poseidonia, in honour of the sea god Poseidon.
