Temple built in 1580 by the Dominicans settled in Oaxtepec. During the Siege of Cuautla in 1812, it was used as a fort and hospital under General Leonardo Bravo. In the mid-20th century, the bell towers were completed and part of the atrium was converted into a cemetery. The cloister was used as a Zapatista Army barracks, a high school, and a cultural center.
