The skulls of 119 men, women and children have been discovered in a newly unearthed section of a 15th century “tower of skulls” in Mexico City. Archaeologists found the skulls in March, but only released the details this month. It brings the total in the tower to around 600. They believe that the structure – the Huey Tzompantli, found five years ago – was one of seven displays of human skulls in the Aztec capital, Tenochtitlan. It’s suspected that at least some of the dead were the victims of human sacrifices.
