The four oldest communities in the borough are La Magdalena Atlitic, San Nicolás Totolapan, San Jerónimo Aculco, and San Barnabé Ocotepec, all of pre-Hispanic origin. The modern community of La Magdalena Atlitic is centered on a church which was founded in the 16th century as a hermitage. The current structure dates to 1760. In 1932, it was named a national monument. The church has a Baroque facade with raised patterns, fronted by a stone paved atrium which has a fountain with an image of the Archangel Michael. The main portal is flanked by Doric pilasters holding up an arch and a cornice to the choir window. Inside, at the base of the arches over the main altar, there are feather designs unique to Mexico.
