Historians have extensively explored the topic of architecture in Mexico City in the 20th century. From the relationships between politics, public patrons, new construction technologies, and new idioms of modernism, the impressive story of architecture in this megalopolis continues to astound and captivate people’s imaginations. Architecture was a channel that politicians used to address housing, education, and health care needs in a rapidly growing city. Yet scholars have not been especially concerned with private construction projects and their influence on the process of shaping and being shaped by the visual representation of Mexico City. Private building projects reveal an alternative reality of the city—one not envisioned by politicians and public institutions. Private construction projects in the historic city center are particularly interesting due to their location. These buildings are built on ancient clay lakebeds and volcanic soil on which the Aztecs first built the city. Not only are these buildings located in the heart of the city, the buildings in the rest of the historic district are also sinking. Any building in a historic district that has withstood the test of time should be an object of interest to scholars. The Torre Latinoamericana is perhaps the only building in the historic district and the entire city that ceases to sink, and instead floats! Located on the corner of Madero and San Juan de Letrán, the building sits at the heart of history, culture, and ancient Aztec clay lakebeds. The Torre Latinoamericana was built between 1948 and 1956 and is one of the most important visual symbols of resilience and modernity in Mexico City today.
