Considered the cathedral of La Cerdanya, it was the seat of an Augustinian canonry first and, later, of the archdeaconry of Cerdanya linked to the bishopric of La Seu d’Urgell.

It is an 11th century church with a single nave with a trapezoidal floor plan topped by a semicircular apse. The apse is very high, smooth on the inside and decorated on the outside with a frieze of blind arches, tangent and supported by simple triangular corbels. The presbytery is connected by an archway on each side with access to the bell tower, located to the north, and the sacristy, located at south. The main entrance is in the frontispiece, where the door retains the original Romanesque ironwork. The bell tower, from the end of the 17th century, is a tower of three superimposed bodies topped with a turret.

It was declared a Cultural Asset of National Interest in 1993.
