Estadio Nacional Julio Martínez Prádanos

The Estadio Nacional Julio Martinez Pradanos is the national stadium of Chile, and is located in the NuNoa district of Santiago. It is the largest stadium in Chile with an official capacity of 46,000, and is part of a 62 ha sporting complex which also features tennis courts, an aquatics center, a modern gymnasium, a velodrome, a BMX circuit, and an assistant ground/warmup athletics track. 

Construction began in February 1937 and the stadium was inaugurated on December 3, 1938. The architecture was based on the Olympiastadion in Berlin, Germany. The stadium became infamous after its use as a prison camp by the military regime following the 1973 Chilean coup d'état.
 
In 2009, a complete modernization plan was unveiled for the stadium and surrounding facilities. President Michelle Bachelet said it would become the most modern stadium in South America. The stadium was built on former farmland, donated in 1918 by farmer Jose Domingo Canas.
