Back-to-back La Liga titles in 1948 and 1949 and the signing of Laszlo Kubala in June 1950, who would later go on to score 196 goals in 256 matches, drew larger crowds to the games.

Construction took three years and ended on 24 September 1957 with a final cost of 288 million pesetas, 336% over budget.
