Square of the Three Cultures

The Plaza de las Tres Culturas is the main square within the Tlatelolco neighborhood of Mexico City. The name "Three Cultures" is in recognition of the three periods of Mexican history reflected by buildings in the square: pre-Columbian, Spanish colonial, and the independent nation. The square, designed by Mexican architect and urbanist Mario Pani, was completed in 1966.

The square contains the archaeological site of the city-state of Tlatelolco and is flanked by the oldest European school of higher learning in the Americas called the College of Santa Cruz de Tlatelolco and by a massive housing complex built in 1964.
