To the east of the promontory, at the mouth of the River Testene, there is a natural sheltered bay, called Foce in ancient times, but which is now almost completely silted up. Before and after the foundation of nearby Poseidonia (c. 625 BC), the Greeks used it for trading with the local people. They gave the promontory the Greek name, Petra (rocky hill), and built a temple on it, dedicated to Artemis, the Goddess of Hunting.
