Part of the footpath PR.1 which crosses the old Medieval bridge of Paderne (Also known as the Roman Bridge) which crosses the Quarteira River close to Paderne castle, Paderne, Algarve, Portugal. The bridge was probably built to serve the castle. The present bridge is built on the pilings of a bridge originally by the Romans to carry the Roman road known as the Via Lusitanorum over river Quarteira. Above the central arch of the bridge there is an inscription that refers the year 1711, probably relating to the year when some works of transformation for consolidation of the structure and recuperation of the walls took place. The Bridge is constructed with three round arches lying on two strong piers.
