Rather than focusing on the monuments and representational architecture of the Plaza, Tlatelolco concentrates on the neighboring residential high-rises. Built in the 1960s under the supervision of modernist Mario Pani, Unidad Habitacional Nonoalco-Tlatelolco is the largest apartment complex in Mexico City. Realized at the zenith of Mexico’s economic boom, Pani’s vision of a “vertical city” beyond class distinctions has itself been shaken up on multiple occasions. Schreiber and cameraman Johannes Hammel capture the fading of an urban architectural utopia.
