Tlalmanalco is a town and municipality located in the far south-eastern part of the State of Mexico. The name is from the Nahuatl language, meaning “flat area.” The municipality's seal shows flat land, with a pyramid on it, representing its pre-Hispanic history, surrounded by small mountains, which is how the area was represented in Aztec codices. The municipality is bordered by the municipalities of Chalco, Ixtapaluca, Cocotitlan, Temamatla, Tenango del Aire, Ayapango and Amecameca. It also shares a border with the neighboring state of Puebla. Much of the municipality borders the Iztaccihuatl-Popocatepetl National Park. For this reason, Iztaccihuatl volcano dominates the landscape. The town has been designated as a “Pueblo con Encanto” by the government of the State of Mexico.
