Unity Arena, formerly known as Telenor Arena, is Norway's largest indoor arena. It is located at Fornebu in Bærum, technically just outside Oslo's city limits, but very much part of the greater Oslo area. The arena was built on the site of Oslo's old airport, Fornebu, which closed in 1998 when Gardermoen took over. The arena opened in 2009 and was renamed from Telenor Arena to Unity Arena in May 2024.
The capacity is up to 25,000 for concerts, making it the only venue in the Oslo region that can host the biggest international touring acts. For sports events, the capacity is around 15,000. In 2024, the venue was upgraded with a flexible system that allows it to be divided into three sizes: a smaller "Box" configuration for 5,000 to 10,000, a medium "Bowl" for 10,000 to 16,000, and the full "Arena" for up to 25,000. This solved a long-standing problem where mid-sized events felt lost in the cavernous space.
The arena hosted the 2025 Men's Handball World Championship, including the final. It is also a regular venue for major concerts, exhibitions and corporate events. Getting there is easy: bus 31 from Lysaker station stops right outside, and there is a large car park. If you are attending an event in Oslo, chances are it might be here rather than in the city centre.
