Built in 1924, the church boasts a solid Neo-Romanesque façade and is the most important example of this architectural style in Barcelona. It consists of a complex formed by the church itself, the parish facilities, and the school of the same name located by the façade and adjacent to Carrer Collblanc. There is a powerful bell tower attached to the façade, made from the same stone as the rest of the complex and in the same Neo-Romanesque style; it has a quadrangular plan and five levels of twin-window openings. It has semi-circular portals with tympanums decorated with narrative mosaics, which tell the life of the saint. The reason for the initial building lies in the large-scale immigration and the growth experienced by this area since the 1920s. It was burnt down, together with the parish house, in July 1936. It was rebuilt between 1940 and 1955 (when the main altar was installed), designed by the architect Josep M. Sagnier, who gave it its current appearance. There are several passages around the church, and perpendicular to the avenue of the same name, that have given rise to an authentic and unique neighbourhood of small, single-family and single-storey houses.
