O2 Arena

The first of the two arenas is O2 Arena in Prague. It was officially opened in 2004, when the Czech Republic hosted its last World Championship. Back then, 422,699 spectators watched games in this brand new multi-purpose arena. Moreover, this World Championship in Prague and Ostrava created and, until 2014, held the record for the highest attendance at any Ice Hockey World Championship.

During the NHL lockout in 2012, 17,182 fans attended a game between Rytiri Kladno with Jaromir Jagr against Kometa Brno, which set the record for the highest single-game attendance in the Czech top league.

The O2 Arena has also hosted games in the two best leagues in the world. It has hosted four NHL games – two between the New York Rangers and the Tampa Bay Lightning in 2008 and two more between the Boston Bruins and the Phoenix Coyotes in 2010. As well, it hosted several Lev Prague KHL home games over the past two seasons, including last year's finals between Lev and Metallurg Magnitogorsk, which amassed the three largest crowds in KHL history.

CEZ Arena

Ostrava's arena was finished and officially opened in 1986. Since then, it has become an important centre for sport and culture in the region and has also held events on a national and international level as well.

In 2003 and 2004, the arena underwent a major renovation and was re-named CEZ Arena. It was officially re-opened on 6th April 2004 with a Jose Carreras concert.
