Zinacantepec is a town and municipality located just west of the city of Toluca in Mexico State, Mexico. The community is named after a small mountain which contained two caves which used to be filled with thousands of bats. Zinacantepec is Nahuatl for Bat Mountain. Its Aztec glyph is a bat on a mountain. In the 18th century, the population of this mountain moved to settle alongside the Franciscan monastery established here in the 16th century. This monastery is the best preserved of a network of missionaries established in the Toluca Valley in the mid 16th century.
