Founded in the year one thousand three hundred twenty-seven by the archbishop of Compostela, Berenguel de Landoira, whose effigy appears in the tympanum of the main façade, where the Epiphany is depicted. In turn, the tympanum of the south side entrance bears the date of the church’s consecration.

The main chapel, which is narrower and lower than the nave, has a magnificent baroque polychrome altarpiece dating from one thousand seven hundred sixty and is covered by a barrel vault, while the Chapel of Pero Carneiro, erected in the sixteenth century and located beside the Chapel of the Gospel, features a shell-shaped vault.
New areas were added later on. Entrances were opened in the sides of the main chapel, one (built in the seventeenth century) leading to the north sacristy, now used to store tombstones, and another (from the sixteenth century) leading to the south sacristy, which features a display of tombstones
Before ending your tour of the church, it is worth visiting the fifteenth-century font, the sixteenth-century tomb of Ioan de Estivadas and the permanent exhibition of tombstones.
Inside there is now a Museum of Tombstone.

In the churchyard, it is worth highlighting the Gothic “cruceiro” (stone cross), in the south, and sixteenth-century baldachin called the “Cristo do Humilladoiro” in the north, as well as the sarcophaguses surrounding the church and the magnificent collection of tombstones (more than five hundred) ranging from the fourteenth to the nineteenth century, which form a unique ensemble.
