The archaeological park covers the heart of ancient Metapontum: the agora, the temples of Apollo Lycaeus and Hera, the theatre cut into a low rise, and the orthogonal street grid laid out by the original Greek settlers. The remains are foundation-level rather than upright, but the scale is impressive — this was a Greek city of perhaps 40,000 people at its peak.
The park lies a few kilometres inland from the modern coastal village. Allow a couple of hours; pair with the Museo Archeologico which is next to the entrance.
