Tlatelolco (Mexico City)
Tlatelolco (Classical Nahuatl: Tlatelōlco [tɬateˈloːɬko], or Tlatilōlco, from tlalli land; telolli hill; co place; literally translated "In the little hill of land") is an area in the Cuauhtémoc borough of Mexico City, centered on the Plaza de las Tres Culturas, a square surrounded on three sides by an excavated Aztec archaeological site, a 17th-century church called Templo de Santiago, a former convent, and office complexes that used to belong to the Ministry of foreign relations and now are property of the National Autonomous University of Mexico.
Historical events of modern Tlatelolco
The Nonoalco-Tlatelolco housing project, built in the 1960s, is served by Metro Tlatelolco. It is also home to the pyramid-shaped Banobras building, which houses a 47-bell carillon. At 125 meters, this is the world's tallest carillon tower. There is also a building covered with white marble that is the former home of the Secretariat of Foreign Affairs (SRE).
In 1967, the Treaty of Tlatelolco signed here, with the aim of establishing a nuclear weapon-free zone throughout Latin America and the Caribbean. Since then, all the region's countries have signed and ratified the treaty.
On October 2, 1968, ten days before the start of the 1968 Summer Olympics the plaza was the scene of the Tlatelolco massacre, in which more than 300 student protesters were killed by the army and police.
On September 19, 1985, many housing buildings were destroyed or suffered damages due to the 1985 Mexico City earthquake. One structure, the "Nuevo León" building, became a symbol of the Mexican people's solidarity during the disaster, represented by a small square in the spot where the building collapsed. Among the many others, Plácido Domingo labored there to help to rescue survivors, mainly because his family lived there.
