The stadium lies at the Anoeta Sports Complex, and is mostly used for football matches where La Liga side Real Sociedad contest their home games.[9] Real Sociedad's Basque rivals, Athletic Bilbao, were also permitted to use Anoeta for their first home game of the 2013–14 La Liga season, as their own new ground (San Mamés) was still under construction.[13] In recent years, it has also been used for concerts, and for occasional Heineken Cup rugby union fixtures by nearby Top 14 club Biarritz Olympique (based in France but very near to San Sebastian).Since the 2009–10 Top 14 season, both Biarritz and fellow Pays Basque club Aviron Bayonnais took home matches to the Anoeta, which is the closest large stadium to their towns.[31] Depending on any issues and delays encountered, it was reported that the construction work could lead to Real Sociedad playing some matches in Bilbao or elsewhere at some point during the period.It was announced that the first match at Anoeta – or the Reale Arena to use its new sponsored title – with all seats in place, a capacity quoted as 39,500 (though with work still ongoing in other areas of the construction)[3][17] would be between the home side and Atlético Madrid on Saturday 14 September 2019, almost exactly a year after the first new stand was opened.
