Chapel with a cruciform floor plan, semicircular gable and attached bell tower. The current appearance of the building bears little resemblance to the original church. The renovation carried out by Josep Maria Pericas gave it a personal style.
The sanctuary consists of two adjoining buildings: the church and the hermit's dwelling. The main façade of the church is aligned with the single-storey building that serves as a dwelling. The entrance door, which is centred on the façade, is arched and protected by a porch with a sloping roof supported by Doric columns. Above the porch is a niche that houses the sculpture of the Virgin of Rocaprevera.
The church is shaped like a single-nave basilica but is made up of several juxtaposed sections. It has a square floor plan on the first level and a circular floor plan on the second, with semicircular openings. The nave has a gabled roof with the ridge parallel to the longitudinal axis of the basilica. It is hidden behind a Baroque pediment. Inside, the choir stands out, with green glazed ceramic tiles between the cairons and wooden beams. This treatment is used on the ceiling of the main nave. The walls of the nave are reinforced by blind arcades that could resemble small chapels, but as they are very shallow, they do not serve as such.
At the base of the apse, there is a covering of well-cut and polished stone blocks, crowned by rows of arcades with stained glass windows and a border imitating saw teeth. It is structured on two floors: one in the lower part, which is below the level of the nave, like a crypt, and an upper one, which serves as a chapel for the Virgin Mary and is accessed via the ambulatory. The interior of the apse is illuminated by multiple polychrome stained glass windows.
It has a transept with a dome, which is square on the outside but forms a false flat coffered ceiling on the inside, covered with a green ceramic roof. On each side there is an oculus that can be opened using a system of shutters. It also has a square bell tower with a cylindrical lantern topped with a conical roof and a weather vane.
The chapel of Santa Maria de Rocapervera was built in 1284 by Monsignor Marco Roca. It was originally an oratory that has been rebuilt three times: as a Romanesque chapel in the 15th century (1429 by Antoni Vinyes) and as a popular chapel in the 18th century (1781).
Finally, it was rebuilt in 1923-1924 due to popular devotion associated with the cult of the Virgin Mary. The current temple is majestic in size and is the result of the so-called ‘Pericas style’, halfway between Noucentisme and Catalan Art Nouveau with borrowings from classical and Romanesque aesthetics.
