A tower of human skulls unearthed beneath the heart of Mexico City has raised new questions about the culture of sacrifice in the Aztec Empire after crania of women and children surfaced among the hundreds embedded in the forbidding structure.
Skulls are seen at a site where more than 650 skulls caked in lime and thousands of fragments were found in the cylindrical edifice near Templo Mayor, one of the main temples in the Aztec capital Tenochtitlan, which later became Mexico City, Mexico June 30, 2017. REUTERS/Henry Romero
