02 World (formerly Color Line Arena) is a multi-purpose arena in Hamburg, Germany. It is located in the city's western quarter of Bahrenfeld, adjacent to football stadium HSH Nordbank Arena. Building the Color Line Arena had cost 83 Million Euro (ca. US $ 121.5 Million). It opened in 2002 and can hold up to 16,000 people. From the inside, it is pretty much a replica of the Hartwall Areena (opened in 1997) in Helsinki, Finland. It is primarily used for handball and ice hockey, and is the home of HSV Handball and the Hamburg Freezers.
