It is built in neo-Classical style and is outstanding for its semi-spherical dome with blue and white stained glass windows with spiral decorations. Inside, the main element is marble, to be found both on the altar and as flooring, which is still original. Annexe to the Basilica is the Comunión Chapel, also in neo-Classical style. Outstanding here is an altarpiece with a statue of the Sagrado Corazón de Jesús. The majority of the sculptures and paintings in the church date from after the Spanish Civil War.
