Plaza de las Tres Culturas

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.

[1][2] 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[3] (built in 1536 by friar Juan de Torquemada[4][5]) and by a massive housing complex built in 1964.

This headquarters now houses a memorial museum called "Memorial 68", opened by UNAM in October 2007,[6] to remember the 1968 Mexican student demonstrations and the Tlatelolco Massacre victims and survivors.

[5] On the south side of the Plaza stands a large stone memorial erected on October 2, 1993, the 25th anniversary of the massacre, in memory of the hundreds killed.
