This temple follows the model defined in the Church of the Gesù in Rome with a Latin cross plan of a single nave, side chapels, transept, and dome. It was built with local stone following the typology of 17th-century Madrid, with a monumental facade between two towers - in this case topped by domes - a central body with four Corinthian columns flanked by two pilasters of the same order on each side, and a central scene with the images of the saints of Madrid. On the other hand, it should be noted that it was heavily damaged during the Civil War when a large part of its chapels, roofs, and priceless works of art were destroyed. These events led to its reconstruction by the architect Javier Barroso, who made some alterations to the original building, including the completion of the towers that had been left unfinished.
