A 17th-century complex built on the site of a church originally dedicated to Saint Lawrence, using materials obtained from a pre-Hispanic shrine dismantled on the orders of Friar Martín de Valencia. In 1541, the cult of Ocotlán was formed due to a Marian apparition in that locality. In 1687, Father Juan de Escobar began the construction of a new sanctuary with materials and labor provided by the indigenous people of the surrounding areas.
