Answer:Three cultures converge here: Aztec, Spanish, and contemporary Mexican. Surrounded by modern office and apartment buildings are large remains of the Aztec city of Tlatelolco, site of the last battle of the conquest of Mexico. To one side is the Church of Santiago.
The Plaza de las Tres Culturas ("Square of the Three Cultures") is the main square within the Tlatelolco neighborhood of Mexico City. The name "<u><em>Three Cultures" is in recognition of the three periods of Mexican history reflected by buildings in the plaza: pre-Columbian, Spanish colonial, and the independent nation. The plaza, 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 (built in 1536 by friar Juan de Torquemada and by a massive housing complex built in 1964.</em></u>
