GC4BDCV-Ponte Romana [Mação]
The bridge rests on two uneven bows, one with a perfect turn and the other with a broken turn, downstream, though with a perfect turn upstream; the width of the pegon is 2.40m. The board is rampant, protected by a parapet. Carving upstream. The broken arch is locked with an iron tie.
1st century B.C. - 01 - probable construction during the Roman period, part of Via Olissipo / Mérida, on the right bank of the Tagus; 13th - 14th century - reinforcement of the structure with broken arch built downstream *1.
*1 - the granite and schist blocks that are not equipped make it difficult to date the bridge precisely, which may be Roman, with repairs during the Middle Ages, or totally medieval.
