Benito Villamarín
As early as 1912, the Spanish architect Aníbal González Álvarez-Ossorio had an initial design of a stadium for the Ibero-American Exposition of 1929. The executive committee has commissioned the architect Antonio Illanes del Río to complete the design in 1923.
Several locations were considered for the new stadium when finally the current location was chosen by commissar Cruz Conde.
The technical study for its construction was carried out by Manuel María Smith who has designed the San Mamés Stadium of Bilbao in 1913.
The construction works were launched in 1923 and finally completed by the end of 1928.
