A small Church, whose primitive Romanesque style appears in good condition.

Built in the second half of the 13th century on a small plateau, it was dedicated to bishop Saint Isidore.

In its structure, the elaborate main portal stands out. The logs of the archivolts connect it to the Romanesque of the city of Porto, the prismatic and cylindrical shafts that support them resemble the Romanesque scattered through the basin of the Sousa and the palmettes in the lines of ashlars connect it to the Braga-Rates axis.

Inside, the light passes through narrow crevices that accentuate the divestment stipulated by the restoration carried out in 1977.

The triumphal arch that separates the chancel from the nave, is slightly broken and devoid of any ornament. The fresco that covers part of the back wall of the chancel stands out.

Dated 1536 and signed by painter Moraes, the pictorial set is presented as a triptych which, read from left to right, shows the Virgin and Child, Saint Isidore and Saint Catherine of Alexandria.

On the side walls, one can still observe, on the left side, Saint Michael weighing souls and, on the right, Saint James, the Apostle, dressed as a pilgrim.
