The Congress Unit, property of the IMSS (Social Security Mexican Institution), can be found inside the Centro Médico Siglo XXI facilities. IMSS has six auditoria and three adaptable rooms. This venue has been used for many congresses, conventions, exhibitions, and national and international work meetings.

The premises are 20 minutes distance from the historical centre of Mexico City; the location is in Cuauhtémoc, which crosses the city from north to south.

In this hospital complex can also be found, besides the Congress Unit, the Oncology, Cardiology, Specialties and Pediatric wards, as well as the Central Blood Bank, the Medical Records Centre and the National Medicine and Surgery Academies buildings.


Its walls have various mural paintings alluding to public health, for instance: Los relieves, by Francisco Zúñiga (1958 – 1959); El aire es vida, by Luis Nishizawa Flores (1958) located in the lobby of the Cardiology Department; and Apología de la futura victoria de la ciencia médica sobre el cancer. Paralelismo histórico de la revolución científica y la revolución social (1958), created by David Alfaro Siqueiros, on the ground floor of the Oncology Unit.
