The Arco di Augusto is the southern entry to the old city, a single white limestone arch that has stood for more than two thousand years. The carved medallions of Roman gods — Jupiter, Apollo, Neptune, and the goddess Roma — are still legible on each face.
The arch sits at the head of Corso d'Augusto, the main north–south axis of Roman Ariminum, which still runs almost dead straight to the Tiberius Bridge at the far end. Walking the whole line in either direction is the quickest tour of two thousand years of Rimini history.
