Hartwall Arena (previously known until 19 March 2014 as Hartwall Areena, called Helsinki Areena, Helsingin Areena or Helsingforsarenan ('The Helsinki Arena') by the national broadcaster Yle) is a large multi-functional indoor arena located in Helsinki, Finland. Opened in 1997, the arena gets its name from its largest sponsor, the beverage company Hartwall, also based in Helsinki.
The idea of building the arena came from Harry "Hjallis" Harkimo in 1994. It was built to be ready for the Ice Hockey World Championships in 1997 and was delivered by the constructor on 11 April 1997. The building is elliptical, 153 metres long and 123 metres wide. 37 meters under ground there is a practice arena which is used by many hockey teams.
The arena is situated next to Pasila railway station, which is the second busiest railway station in Finland, 3.5 km north of Helsinki Central.
Total capacity in ice hockey games is 13,349 (all seats). The arena is convertible for various events. For sport events, the capacity is about 10,000, about 14,000 for basketball, for concerts about 13,000, and as an amphitheatre, 3,000-5,000.
