Guided Tour of Plaza de Tres Culturas, Tlatelolco

The Plaza de las Tres Culturas in Tlatelolco, Mexico City, brings together three eras of the city's history in one place. At its center are the excavated pyramids and temples of Tlatelolco, the twin city of the Aztec capital Tenochtitlan and home to its great market. Beside them stands the Templo de Santiago, a 17th-century church built by the Spanish partly with stone from the Aztec temples, and around them rise the modern towers of the Nonoalco-Tlatelolco housing complex. The plaza has witnessed key moments in Mexican history, from the last Aztec resistance against the Spanish in 1521 to the massacre of student protesters on October 2, 1968.
