It began to be built in the mid-seventeenth century to about 1651, as part of a convent for the Carmelite order. However, the order did not settle in the village, so the priest Pedro Rincon de Ortega, who paid for the work, then, requested that the Franciscans of San Diego take over the church and convent, which occurred around 1664. In the late nineteenth century, between 1894 and 1895, it added a front porch and balustrade, or a small railing. He retired in 1916, the same year when the porch was rebuilt. The dressing room of Our Lady of San Diego was built behind the Temple of San Diego in the late eighteenth century. It is an outstanding example of the Baroque architecture of Aguascalientes. Noted for its large dome, the shrine was built between 1792 and 1795 at the expense of Captain Juan Francisco Calera, so that the priests could change their vestments at the Immaculate Conception which is worshiped at the main altar of the Temple of San Diego. In January of 1779 it was blessed by Juan Ruiz de Cabañas, Bishop of Guadalajara, and then, the first mass was celebrated in this room.
