The team played their home matches at the Unión Telefónica Stadium on Potosí street in the Barrio Inglés (current Barrio Pueyrredón).[4] Inaugurated in June 1936, it was the first venue of C.A. Racing.[2]
Architect Lange was the author of the project for a new stadium. That project was supervised by engineer Wieland. The grandstands were built by César Gervasi and Conrado Grotstchl. Works had a cost of m$n81,000.[5]
The stadium was inaugurated on 27 May 1948[1] under the presidency of Rubén Monguzzi.[6] Celebrations ended with a friendly match between Racing and Club Atlético Belgrano, champion of Liga Cordobesa. Racing won 4–3.[6] The recently inaugurated venue had a 70 metre-width official grandstand for 4,000 spectators with 25 tiers, a popular stand (capacity of 2,000) with 12 tiers, and the stalls (capacity for 300 people).
In May 1976, the stadium was given the name "Miguel Sancho" as a tribute to a former president that leaded the club for 24 years.[2] Mario Spirópulos (in office 1976–89)[7] was the president by then.[1]
The stadium was refurbished in 1984 under the presidency of Donato Antonacci.[5] One year later, a lighting system was installed.[2]
