skulls of people who were ritually sacrificed.
Part of this tower, called Huei Tzompantli, was uncovered in 2015. The new discovery brings the total number of skulls in it from men, women, and children to 484.
The Aztecs ritually sacrificed people to appease their gods. They displayed the heads of their dead on enormous, cylindrical racks called tzompantli, constructed using rows of skulls mortared together. The Aztecs used these towers to show off their empire s might to enemies and invaders.
Last week, Mexico s National Institute of Anthropology and History (INAH) announced that researchers had discovered a section of one such tower under the ruins of Mexico City s Templo Mayor. It contained 119 skulls from men, women, and children.
