The construction of the University of the National Autonomous University of Mexico meant an unrepeatable moment for the architecture of the country. At that time, unique and unrepeatable factors were able to unite the great majority of the great talents of their time. The result materialized the ideals and achievements of a generation and catapulted the architectural, artistic and cultural work of Mexico to new levels. The construction of this unprecedented huge project meant a great challenge for architecture and the construction industry. ICA, a young construction company, was the protagonist of the feat and its subsidiary "Aerofoto", a great vanguard initiative, was in charge of documenting the construction process. This volume documents the construction of CU chronologically, grouped by decades and accompanied by small texts, the images show us the prowess of its construction. A huge nostalgic content portrays a Mexico in the middle of the forge, a Mexico City in explosive growth. Some of the published images are unpublished.
