After the arrival of Augustinian monks shortly after the Spanish Conquest of Mexico, this church and its now former monastery were built by Fray Andrés de la Mata de Barrios in 1550. The church is dedicated to the Archangel Michael and was built using Indian labor pressed into service by the monks. This church is typical of the fortress-style churches built by the Augustinians in the 16th century. The facade is Plateresque style with paired columns and with a window in the choir area. The bell tower is annexed and joined with the facade. It has a crown and bell gables.
