Tecoaque is a Mesoamerican archaeological site, located in western Tlaxcala state, central Mexico, close to Calpulalpan. The site was inhabited by the Acolhua, one of the three ethnic groups making up the Aztec Empire (their capital being Tetzcohco, one of the three seats of Aztec power). Tecoaque had many white-stucco temples and was the home to approximately 5,000 people, mostly priests and farmers.
