Bridge built over the Cavalos River, with a deck approximately 50 m long and 3 m wide. It probably forms part of the same road link as the Roman road of Pedra da Sé, serving as a connection between the Roman civitas of Bobadela and that of Viseu. It has only one arch with a perfect semicircular span, and the pavement that forms part of the deck is the result of intervention after the time of construction. It has been classified as a Property of Public Interest (IIP) since 1990, by Decree No. 163 of July 17, 1990.

The Roman Bridge of Sumes stands over the River des Chevaliers, shrouded in mystery. Although its foundations appear to be Roman, the exact date of its construction remains uncertain. An inscription reading "80 AD" found on a nearby wall suggests its origin, but some historians believe it refers to an ancient spring. In the surrounding area, traces of medieval paving can still be seen. Regardless of the bridge's uncertain age, it is classified as a Property of Public Interest, having witnessed centuries of history.
