San Agustín de las Cuevas

The area come under control of the Spanish after the fall of Tenochtitlan, and the village's name was changed from Tlapan to Villa de San Agustin de las Cuevas in 1645. San Agustin is the area's patron saint, and the name of the parish church built by the Dominicans in the early 16th century. The last part means “of the caves,” referring to the many caves and caverns formed in the area by an eruption of the Xitle volcano in 100 CE.[3][6] Initially, this area south of the Valley of Mexico was part of lands administered by authorities in Coyoacán.[6] During the colonial period, the old village of Tlalpan was a modest farming village, known for its orchards and extensive forests. The latter made it attractive as a retreat for the wealthy of Mexico City.[4] These elite established country homes and haciendas, which eventually became the economic base of the area.[3] By the 18th century, the village of Tlalpan was large enough to be an ecclesiastical center.[6]
