As we go through our tour of the Lands of Iria, if we access it from the south, from the province of Pontevedra, we will cross the waters of the famous Rio Ulla on a bridge which origins were Roman. It currently consists of 13 hollow openings, some with pointed vaults and others that are half-point. Despite the reforms made to the structure over the years it is still possible to appreciate the majesty of the Roman period.
Built between the years 25 B.D. and the first century A.D. being the emperor of Rome Octavian Augustus. Important communication channel, the most important reform since its construction was done by Master Mateo in the year 1161, author of the Portico de la Gloria. The Ulla is the natural border between the provinces of Pontevedra and Coruña, the bridge serves to communicate the two provinces and especially two neighboring villages as Pontecesures and Padron. Thus becoming a symbol of unity.
