Its construction took longer than 150 years, its approach following the example of Il Gesú in Rome, with its stone facade bearing a large window and sombre decoration with enormous corinthian columns that framed the niches of the church's saints like an altar. The dedication to San Ildefonso, a bishop from Toledo in the VII Century, can be seen on the central relif of the "Imposition of the Chasuble". This scene and the brick towers are the only adaptation to the surroundings.Recently restored, the church is open to the public and offers the chance to see the narrow tower of the Cathedral close up and enjoy the panoramic view of the entire city from the two wide towers with their large openings on their four sides.
