Huapalcalco Pyramid

Huapalcalco ("place of the wooden house") is an archaeological site 5 km north of Tulancingo, Hidalgo, Mexico, with evidence of human occupation dating to 9000 BCE including cave paintings of hunting scenes in Tecolote Cave. The main feature is a compact three-sided pyramid with Teotihuacan influence, alongside 28 unexcavated mounds covering smaller pyramids. First excavated in 1954 by Florence Muller and Cesar Lizardi, the site yielded a Maya-influenced stela, Totonac yokes, and a round altar. Tradition holds that the god-king Topiltzin Quetzalcoatl resided here before ruling Tula.
