Nacional Monument, built in the X century. With a fantastic view from the top of the Lamego city. Visit free.

The chapel of São Pedro de Balsemão is located in a small plain along the Balsemão river banks. Although the chapel is now part of a seventeenth century manor, its interior still preserves 10th century traits, namely Mozarabic Iberian architecture techniques, which make it one of the rare examples in portuguese territory. Another remarkable element of this small temple is D. Afonso Pires sarcophagus as well as the Roman influence, well visible in several inscribed stones, reused in the construction of the chapel walls.

The foundation of this Franciscan male convent began with the donation of the surrounding land by Don Francisco Coutinho, Count of Marialva, in 1525, as part of an earlier fortified tower from the 14th century. Highlight for the eight boards painted in 1533-1534 by the so-called "Masters of Ferreirim" on display at the Interpretive Center.
