Its inaugural game was played on 2 September between Zaragoza and Portuguese side Vitoria de Setúbal and ended in a one-all draw.

In November 2014, Osasuna was forced to sell the stadium to the regional government of Navarre (Navarra) because of the club's huge economic crisis, threatening its continued existence.

In early 2019, the club's members voted in favour of an expansion of the stadium to almost 24,000 seats (in preference to modest upgrading to meet league requirements with no increased capacity)[6] and then chose their favourite from several projects submitted by firms the previous year.

[7] The work, including the addition of an extra tier of seats on the three smaller stands and corners to almost reach the height of the grandstand, the installation of 1,300 rail seating places at the south end of the ground,[8] a new roof structure over the ring of the stands augmented by colour-coordinated external cladding,[9] a club museum and improvements to the players' area, media and corporate facilities and hospitality, began in late 2019 and was completed in early 2021.

[10] It was hoped to coincide with Osasuna's centenary but this proved difficult due to the COVID-19 pandemic in Spain; however, the fact that all matches were played in empty stadia during the crisis allowed the work to carry on with minimal interruption, although at a slower pace than anticipated.
