A large monolithic sculpture that was excavated in the Zócalo, Mexico City's main square, on December 17, 1790. Measuring about 3.6 metres (12 ft) in diameter, 1.22 metres (4 ft) in thickness and weighing 24 tonnes,[2] the original basalt version is presently on display at the National Museum of Anthropology in Mexico City's Chapultepec Park. It is often informally considered to be one of the national symbols of Mexico.
