| At the time of Spanish conquest in 1521, Templo Mayor stood nearly 40 m (130 ft) high. Its rectangular base was about 80 by 100 m (260 by 330 ft) wide. Constructed during a century of increasing Aztec power, Templo Mayor lay at the center of Tenochtitlán’s sacred precinct and was the site of thousands of human sacrifices. Spanish conquistadors destroyed the temple and began building a colonial city upon its ruins. Excavation of the temple, located in modern-day Mexico City, began in 1978. |
