This 16th-century monastic complex was built by the Augustinians and stands out from the other buildings in the region due to its façade, which is entirely decorated with simulated stucco ashlar and medallions with the monograms IHS and XPS.

Founded in 1534 by Friar Jorge de Ávila, it has an atrium, a processional path, and two side chapels.

The temple has a single nave with a barrel vault and a tower that was built later.

In the upper and lower cloisters, one can admire the mural paintings that adorn them, featuring Augustinian saints and motifs from the medieval, Renaissance, and Moorish periods. One notable mural contains the Lord's Prayer written in Nahuatl.
