Teotenango, from the Nahuatl words “teotl” (God) “tenamitl” (wall) and “co” (place), translates to the Place of the Divine Wall. A Pre-Columbian temple and fort complex built in 650 A.D., it overlooks the Valley of the Matlatzinco in the central Mexican highlands. It was abandoned in 1540 and lies in ruins.
