In the center of the city were the public buildings, temples, and palaces. Inside a walled square, 500 meters to a side, was the ceremonial center. There were about 45 public buildings, including: the Templo Mayor, which was dedicated to the Aztec patron deity Huitzilopochtli and the Rain God Tlaloc; the temple of Quetzalcoatl; the tlachtli (ball game court) with the tzompantli or rack of skulls; the Sun Temple, which was dedicated to Tonatiuh; the Eagle's House, which was associated with warriors and the ancient power of rulers; the platforms for the gladiatorial sacrifice; and some minor temples.[9]
