They then tossed the victims’ lifeless bodies down the steps of the towering Templo Mayor.
Andrés de Tapia, a conquistador, described two rounded towers flanking the Templo Mayor made entirely of human skulls, and between them, a towering wooden rack displaying thousands more skulls with bored holes on either side to allow the skulls to slide onto the wooden poles.
