Incredibly well maintained archeological site. It has a fascinating history: the name "Three Cultures" is in reference to the 3 periods of Mexican history: pre-Columbian, Spanish colonial, and the independent nation. All periods are represented by buildings in this square.
The square contains the archaeological site of the city-state of Tlatelolco (pre-Colombian) and also the oldest European school of higher learning in the Americas, called the College of Santa Cruz de Tlatelolco (built in 1536).
