The Basílica of Guadalupe is a church for uniting pre-Hispanic Indian mysticism with Catholic beliefs and the construction started in 1531 until 1703. It is characterized by its Doric interior and marble statues of Juan Diego and Fray Juan de Zumárraga. The church was granted basilica status by Pope Pius X in 1904.In 1921 a bomb planted in a flower vase near the altar by a anticlerical activist exploded causing great damage to the interior of the building. The modern basilica was built between 1974 and 1976 by the Mexican architect Pedro Ramírez Vásquez. It is a circular building constructed in such a way as to allow maximum visibility for the image to those inside. The structure is supported by 350 pilots that prevent the basilica from sinking with the rest of the ground.
