The monastery of San Mateo Apostol in Atlatlahuacán was built by the Augustinians around 1570 over the remains of a pre-Hispanic temple in the highest part of the town. The Stations of the Cross in the atrium are represented by small chapels on the exterior of the atrium wall. It has two roofed chapels in its atrium, one of which has a mural of the genealogical tree of Saint Augustine. The façade of the church is exceedingly tall, common in Augustinian constructions, extending about 50 meters in height. Fresco paintings covered most of the interior of the complex, with vaults that combine Moorish elements with those of the Italian Renaissance. Confession booths were constructed in an “s” pattern in the wall dividing the church from the cloister area. In the cloister, one of the principal attractions is one vault on the ground floor, decorated with a chain made with images of the Sacred Heart of Jesus. The upper level serves as the home of the parish priest.
