Estadio El Llano, Municipal sports complex in San Miguel, Santiago, Chile.

Estadio El Llano, officially Estadio Luis Barros Borgoño, is a sports ground in San Miguel, Santiago, built on 32,000 m² of land in El Llano Subercaseaux. The architect Ricardo González Cortés designed it, and by 1923 it had a football pitch with an athletics track, three tennis courts, changing rooms for athletes and two chalets.

The facility emerged in 1921 when credit bank employees founded a football club and later acquired land for expansion. A few years later, the site became the place where a club was established that would become the nation's most prominent.

Colo-Colo was founded at the stadium on 19 April 1925, when players led by David Arellano left Magallanes; Luis Contreras chose the new club's name there. The ground had been built for the employees of the Caja de Crédito Hipotecario, and its rooms hosted the social events of the period.

The stadium sits in El Llano Subercaseaux, in San Miguel, on a 32,000 m² plot; the grounds were laid out by architect Ricardo González Cortés. Access is from the surrounding streets of the San Miguel district, south of central Santiago. The site holds a football pitch with an athletics track, three tennis courts, changing rooms and two chalets, so different areas serve different sports.

Colo-Colo was founded on 19 April 1925 at this stadium, when players led by David Arellano left Magallanes; Luis Contreras proposed the new club's name.
