 Archaeologist José García Payón excavated the monumental architecture at Calixtlahuaca in the 1930s and restored a number of temples and other buildings.Most notable are Structure 3, a circular temple dedicated to the Aztec wind god Ehecatl, and Structure 17, a large royal “palace”.The architecture and stone sculpture at the site is similar to that of other Middle to Late Postclassic period (AD 1100-1520) Aztec sites in central Mexico.
