About the O2 Arena (Prague)
The O2 Arena in Prague is an arena built for many kinds of events and opened in 2004 under the name Sazka Arena. HC Sparta Prague plays its home games there in the Czech Extraliga, and it also stages concerts and other large events. It has been a host venue of the Ice Hockey World Championships three times, in 2004, 2015 and 2024. Other events include the Euroleague Final Four in 2006, the 2012 Davis Cup final, four Fed Cup finals, the European Athletics Indoor Championships and the first Laver Cup, which was a men's tennis tournament.
The idea of a new arena in Prague followed the Czech national team's Olympic gold in 1998 and its three straight world titles from 1999 to 2001. Its main backer was Sazka, a Czech betting company. Construction began in September 2002 and had its share of problems. It opened in March 2004, ready for the men's world ice hockey championships of 2004, and it was renamed O2 Arena in March 2008. Sazka filed for insolvency in March 2011 because of what it owed for the arena's construction, among other problems.
HC Slavia Prague played at the arena from its opening until 2015. Slavia won the 2008 national championship there on home ice, taking Game 7 of the Extraliga finals 4–0 before a crowd of 17,117 that was a league record at the time. The club later moved back to its smaller former home, and the arena reached an agreement with Sparta Prague on June 24, 2015. In 2014 it hosted the home games of HC Lev Prague in the Gagarin Cup Finals of the Kontinental Hockey League, which drew the three largest crowds in that league's history.
