Eyravallen, currently known as Behrn Arena for sponsorship reasons, is a football stadium in Örebro, Sweden and home stadium for Örebro SK in Swedish top flight Allsvenskan. The stadium holds 12,645 people and was built in 1923. The stadium has been developed during the last couple of years. The attendance record at the arena was against the local rival of Degerfors IF having 20,066 people watching the game 8 June 1961, and the record in the modern-day arena is 12,523 being during the game against Hammarby IF, on 13 May 2018. The stadium's grass is astroturf since 2003, and Örebro was the first top-flight club in Sweden to have that playing surface. This was in part due to the harsher winters in Örebro compared to coastal and further southern areas. Football club KIF Örebro and American football club Örebro Black Knights also became tenants of the stadium.
