Festningen 2026: guide to Trondheim's summer fortress festival

Festningen returns to Kristiansten Fortress in Trondheim on 4-5 September 2026, drawing around 18,000 festival goers across two nights of pop, hip-hop and electronic music. There is no camping. This is a city festival: you stay in Trondheim, walk or take the bus up to the fortress gates, and see DJ Snake, Sigrid and Marcus og Martinus perform against the old stone ramparts. This guide covers everything you need to know for the 2026 edition, from the lineup and lockers to transport and what to leave at home.

The venue: Kristiansten Fortress

Kristiansten Fortress (Kristiansten Festning) sits on a hill above Trondheim's old city quarter, built in 1681 after a fire levelled much of the town. The fortress held strategic importance for centuries; today it is one of Norway's best-preserved 17th-century military structures and a popular viewpoint over the city and Trondheim Fjord. For two evenings every September the open grounds become the festival site, with stages set into the ramparts and standing areas spread across the upper plateau. The elevated setting and compact layout give the event a different feel from flat-field festivals, and most of the standing area has clear sightlines to the stages. The address is Dronningens gate 11, Trondheim (source: festningen.no).

Event Lockers at Festningen 2026

Volt provides Event Lockers at Festningen. Once you book, you receive your locker number and access code by email and SMS before the festival starts, so there is nothing to sort at the gate. You can lock your bag or jacket in and retrieve it any time during the festival's opening hours. Pre-order prices for 2026 (source: festningen.no/skap):

• Single day: 180 kr
• Full weekend: 290 kr

Booking in advance saves up to 70 kr compared with on-site prices. Lockers sell out before the gates open most years, so checking availability early is the better call. Book through the festival's locker page: festningen.no/skap.

Getting to Festningen in Trondheim

Kristiansten Fortress is inside the city, which makes transport simpler than most festival sites. The options from central Trondheim:

• On foot: the walk from the main shopping streets to the fortress entrance is roughly 15-20 minutes uphill.
• Bus: ATB route 63 stops at Festningsgata, the closest bus stop to the gates. Routes 1, 2, 11 and 25 also run nearby. Current timetables and maps at atb.no.
• Train: Trondheim S (the central station) is about 17 minutes on foot from the fortress.
• Taxi or ride-share: drop-off along Dronningens gate works well for the uphill approach to the entrance.

The festival does not provide on-site parking for festival goers. Public transport is the practical option for most.
