The church, which could have been founded in the year 1164 according to the date inscribed behind the main altarpiece. According to documentary evidence, only the presence of the Order of the Holy Sepulchre is accredited in the place, gaining great importance in the mid-15th century as the head of the commandery until it was replaced by the Order of Saint John of Jerusalem, then becoming dependent on the commandery of Pazos de Arenteiro.
The church is rural Romanesque with a Latin cross plan of a single nave, formed by four sections limited by thick buttresses that barely protrude from the outer wall. Over the nave, a gabled wooden roof. The exterior finish features a belfry with two arches.
It is notable for a certain air of monumentality due to its height proportion in relation to its plan, which is higher than the standards of the area. The apse is semicircular, with three windows framed by double columns with vegetal capitals, supporting semicircular arches. The exterior decoration also includes corbels with vegetal and geometric motifs and representations of animals and fantastic beings.
To the west, the main façade with modillions supporting the cornice and in the middle, metopes with rosettes. The main entrance door to the temple has three archivolts resting on columns with geometric, vegetal, and animalistic capitals. The bilobed tympanum has a patriarchal cross inscribed in a circle and rests on two corbels.
On the northern façade, the door also has a tympanum, with two cross pattées and a floral motif, resting on two simple smooth corbels. It opens with a semicircular arch reformed on the basis of a primitive compound arch reminiscent of the Mozarabic style. Two columns with capitals complete the ensemble.
