Pyramid of the Sun

The Pyramid of the Sun is the largest building in Teotihuacán and one of the largest in Mesoamerica. Found along the Avenue of the Dead, in between the Pyramid of the Moon and the Ciudadela, and in the shadow of the massive mountain Cerro Gordo, the pyramid is part of a large complex in the heart of the city.
