The Agri valley has always been a privileged natural traffic route, since pre-protohistory, because it connects the inland and mountainous areas of Lucania with both coasts, the Ionian following the river route, and the Tyrrhenian through several passes of considerable importance, both for transhumance routes and to connect, in historical times, the people of the interior with the Ionian and Etruscan-influenced Magna Greek colonies on the Tyrrhenian. With Romanisation, Lucania was immediately provided with military roads, i.e, routes by which the central power could control peripheral areas by sending military contingents.
