The Plaza México situated in Mexico City is the world’s largest bullring. This 41,262-seat facility is usually dedicated to bullfighting, but many boxing fights have been held there as well. The bullring opened on 5 February 1946 and annually since then, that date marks the Corrida de Aniversario (a bullfight event).
The Plaza México replaced the ancient bullring Toreo de la Condesa in the Condesa neighbourhood that was overwhelmed by the rapid development of the Mexican population. This building was erected beside the football stadium Estadio de la Ciudad de los Deportes (now Estadio Azul).
