The Great Pyramid of Tenochtitlan, also known as the Templo Mayor, was a significant religious structure in the ancient city of Tenochtitlan, the capital of the Aztec Empire. Built in the 14th century, it served as a central place of worship dedicated to the gods Huitzilopochtli and Tlaloc. The pyramid was part of a larger complex that included various temples and ceremonial spaces. The pyramid was originally about 60 meters tall and featured twin temples at its summit. It was constructed in several phases, with each layer representing different periods of the city's history. The Templo Mayor was a focal point for Aztec rituals, including human sacrifices, and played a crucial role in the cultural and religious life of the Aztec people.
