Archaeologists discovered a tower of more than 100 human skulls buried beneath the center of Mexico City.
The structure, called Huei Tzompantli, was originally discovered by Mexico’s National Institute of Anthropology and History (INAH) in 2015. But after a return to the site earlier this year, the team discovered a tower of 119 skulls, previously hidden,
The tower is believed to have been part of a skull rack, one of seven collections that stood in the old Aztec capital Tenochtitlan. It was likely created in honor of Huitzilopochtli, the Aztec god of sun, war, and human sacrifice.
The INAH has now reported a total of 484 skulls found at the site, dating between 1486 and 1502. It is believed that the temple was destroyed when conquistadors invaded the Aztec Empire and Hernan Cortes captured Tenochtitlan in 1521.
