Ponte Romano ("Roman Bridge"), also known locally as Ponte del Diavolo or Ponte di Annibale, is the oldest man-made structure in San Mango, built in about 100 BC. The bridge is composed of bricks, mortar and cobblestone taken from the Calore river that flows beneath it. It was part of the old Napoletana road that passed by the Sant'Anna chapel, curving down to the Calore River.
