Its origin possibly dates back to the 11th century, although from the 12th century onwards it underwent various alterations and was progressively enlarged.

It was conceived as a temple with a rectangular nave, semicircular apse and double atrophied presbytery, but successive interventions maintained few elements of the original construction, such as the semicircular apse.

Some authors date its construction to between 1060 and 1070, although, as is the case with all the churches in the so-called "Larredense circle", it is still shrouded in controversy regarding its dating and stylistic affiliation.

In 1982, the Association of Friends of the Serrablo carried out the restoration of the roof.

It is a rectangular church with a semicircular chevet facing east, built with ashlars at the chevet and masonry combined with rough and large ashlars in the rest.

It has a semicircular chancel facing east, a main nave, plus another on the south side, two side chapels open on the north side and a tower that rises above one of these chapels.

It was originally a building with a single nave, a double atrophied presbytery and a semicircular apse. To this original nave, another narrower nave with a straight chancel was added on the south side, connected to the main nave by two former arches. Two chapels were opened on the north side and later, the sacristy.

On the south wall is the doorway with a semicircular arch, with large voussoirs, which starts from a relief at the base of the jambs with motifs of grooves and inverted mullioned motifs. The keystone bears the anagram IHS.

The tower rises above the Gospel chapel with ashlars in the lower part and masonry in the rest, forming a single body. The interior consists of three flat wooden floors. It is covered with a hipped slab roof on the outside and a hemispherical dome on the inside.
