The Sinan Erdem Dome, among the largest indoor arenas in Europe, hosted the final of the 2010 FIBA World Championship, the 2012 IAAF World Indoor Championships, and the 2011–12 Euroleague Final Four. Prior to the completion of the Sinan Erdem Dome in 2010, Abdi İpekçi Arena (completed in 1986) was Istanbul's primary indoor arena; it hosted the finals of the 1991–92 FIBA European Championship and Eurobasket 2001. Several other indoor arenas, including the Beşiktaş Milangaz Arena (which opened in 2004), have also been inaugurated since 2000, serving as the home courts of Istanbul's sports clubs. The most recent of these is the 13,800-seat Ülker Sports Arena, which opened in 2012 as the home court of Fenerbahçe's basketball teams.
