## History
### Development and construction

A city stadium was considered in 1955, with the intention that it could function as host for the 1962 FIFA World Cup in Chile. The initiative was led by two professionals from Antofagasta, Miguel Bascuñán Pavez and Alberto Calvo Nieto, who formed the "Pro-Construction Committee" in 1958 with the aim of solidifying the project. It was decreed by law (13,080 from the Ministry of the Interior of Chile) that the lands then-occupied by the Club Hípico de Antofagasta (Riding Club of Antofagasta) be expropriated to the municipality for the construction of the stadium, stipulating the amount to be paid, the agreement being effective on January 31, 1959. The amount decreed was 300 million CLP.
The 1960 Valdivia earthquake caused severe damage to several stadiums in Chile, upsetting the calendar for the World Cup. On September 30, 1960, the Corporation of Development of Chile (Corfo) provided economic contributions toward the construction of the Antofagasta stadium, under the condition that work began before March 1, 1961. Mayor Santiago Gajardo handed over the land to the Santiago-based Wedeles, Balmaceda, Mathieu and Company, Ltd. on January 5, 1961. The work officially began on January 18. However, due to financial problems, construction was postponed and the committee responsible was dissolved. Work resumed on July 3, 1961, with the demolition of the riding club's facilities. Calvo and Bascuñan reformed the construction committee and secured government and private funding, though they'd lost the opportunity to host the 1962 World Cup. On July 9, 1962, Razmilic and Co. restarted the unfinished work.

### Inauguration

   Because there the youth is educated in the physical, muscular and this, once achieved, reports immense benefits for the family and community:
