Acatlán is a town and municipality located in the Mexican state of Hidalgo, about 10 km northwest of the city of Tulancingo and 147 km from Mexico City. The main landmark is the San Miguel monastery which was built in the 16th century. It is partially in ruins but there have been efforts since the 1980s to restore it. Acatlán comes from a Nahuatl phrase which means “near the reeds”.
