Although a church was built on its foundations, we have detailed descriptions of the main temple, known today as Templo Mayor. Four roads converged at the temple,which sat on a vast base, representing the terrestrial earth. Large incense braziers, with serpent heads and cauldrons on all four sides, were set up to receive offerings. From its base, the temple rose in four platforms,representative of the celestial levels of the cosmos, until it reached the top level, where there were two temples dedicated to Tlaloc and Huitzilopochtili. Two parallel stairs led separately up to the temples, to the summit.Huitzilopochtili, whose temple was to the south, was the Mayan warrior god who fought his brother Centzon Huitznahua and his sister Coyolyauhqui immediately after birth. He defeated them and threw their dismembered bodies down the mountain, a sacrifice marked by a round tablet at the foot of the stairs.
