In the parish of Ferreira is one of the gems of the heritage of the Terras de Sousa, the Ferreira Monastery. With a strong influence, in the Middle Ages, on the settlement and agricultural and cultural development of the region, the Romanesque Church of S. Pedro de Ferreira that has reached our days is an impressive testimony of 12th century architecture. In it you can find influences as diverse as those of the school of Zamora, evident in the portico; from the school of Coimbra, visible in the capitals and, still, from a local school, with parallels to Unhão, in the beautiful stonework of the two side doors. The Church is of impressive strength and robustness, of a single nave, with buttresses attached outside and inside. It has an exterior nartex with a bell tower that, although from a later period, articulates harmoniously with the construction of the century. XII. The entrance porch is made up of five arches with simple columns and profusely worked capitals.

Triumphal Arch: Inside its triumphal arch of great height, with two smooth archivolts without decoration topped by friezes (mitraic arch, in triangle, differs from the broken Gothic arch)
