History
The idea of building a new arena in Prague came on the heels of the "golden era" of Czech ice hockey: winning 3 gold medals in a row. The arena was proposed to be built in time to host the 2003 World Championship tournament in ice hockey, but due to unforeseen complications with the investors, the ice hockey governing body had to switch that tournament to Finland. The arena's main backer then became Sazka a.s., a Czech betting company.

The construction of the arena (which began in September 2002) was not without problems, but it finally finished in time to host the 2004 tournament.

In March 2008 the building was renamed O2 Arena.
