Helsinki Halli (formerly Hartwall Arena) is a large multi-functional indoor arena located in Helsinki, Finland. It was opened in April 1997. The arena is convertible for various events. The total seated capacity during ice hockey games is 13,349 (about 14,000 for basketball, for concerts up to 15,000) and as an amphitheatre, it is significantly reduced to between 3,000 to 5,000. The Russian-owned arena has been unused since March 2022 due to EU sanctions related to the Russian invasion of Ukraine. The main sponsor, Hartwall, also ended its sponsorship and the arena's name was changed. Construction and facilities The initiative for 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. It also has a practice arena 37 metres underground, used by many hockey teams. It is connected to a multi-storey carpark, which has a total capacity of 1,421 vehicles. The arena is situated next to Pasila railway station, which is the second busiest railway station in Finland, 3.5 km north of the Helsinki Central railway station. Other and former names The national broadcaster Yle calls the arena "Helsingin areena" or "Helsingforsarenan" ("The Helsinki Arena" in Finnish and Swedish). The newspaper Helsingin Sanomat calls it "Helsinki-areena". It was branded as "Hartwall Areena" from its opening until 2014, and as "Hartwall Arena" thereafter until 2 March 2022. The beverage company Hartwall, also based in Helsinki, was its largest sponsor, and thus got the naming rights. Hartwall ended its sponsorship in March 2022, to avoid association with the Russian main owners of the arena, Roman Rotenberg and Gennady Timchenko, in the wake of the 2022 Russian invasion of Ukraine.
