Roman bridge, located in the village of Catribana (São João das Lampas, Sintra), crossing over the Samarra river. The bridge is composed of a single arch and parapet, with several restorations and changes over the centuries. Probably it was part of a secondary Roman road that connected the several villa of the Olisipo region. Remains of a Roman road, necropolis and some mosaics and ceramic fragments were also found nearby.
