Festningen

Festningen is a two-day music festival in Trondheim, described by its organisers as one of Mid-Norway's largest music festivals. The 2027 edition takes place on 3 and 4 September. The festival has an 18-year age limit and two stages, with an accessible platform offering good sight lines to both, and it carries the Balansemerket mark against discrimination and sexual harassment in the cultural sector. OBOS is its main sponsor, and the organisers give Dronningens gate 11 in Trondheim as their address.
