Conjunto Urbano Nonoalco Tlatelolco is the largest apartment complex in Mexico , and second largest in North America , after New York 's Co-op City . The complex is located in the Cuauhtémoc borough of Mexico City . It was built in the 1960s by architect Mario Pani . Originally , the complex had 102 apartment buildings , with its own schools , hospitals , stores and more , to make it a city within a city . It was also created to be a kind of human habitat and includes artwork such as murals and green spaces such as the Santiago Tlatelolco Garden . Today , the complex is smaller than it was and in a state of deterioration , mostly due the effects and after effects of the 1985 Mexico City earthquake . This quake caused the immediate collapse of the Nuevo León building with others being demolished in the months afterwards . Further earthquakes in 1993 caused the condemnation of more buildings . In addition to the lost buildings , many residents eventually undersold or abandoned their apartments , as repairs were either never made or made poorly
