Festningen 2026: the practical guide to Norway's fortress festival

Festningen is one of Central Norway's largest music festivals, set on the hillside grounds of Kristiansten Festning in Trondheim. In 2026 the event runs two days, September 4 and 5, with 15 artists, 18,000 festival goers, and two stages set inside fortress walls that have stood since the 1680s. If you have a ticket or are thinking about going, this covers what you need to know.

Dates and venue at a glance

The venue: Kristiansten Festning

Kristiansten Festning sits on a ridge above the Nedre Elvehavn area of Trondheim, roughly fifteen to twenty minutes' walk from the city centre. The fortress was built in the late 17th century and overlooks the city and the Trondheim fjord. Concerts take place in the open air on the fortress grounds, with the fortification walls forming a natural backdrop and two stages facing the audience downhill.

The site is compact but laid out across different levels, so expect some walking between stages and food areas. The ground is a mix of grass, gravel, and cobblestone, so comfortable footwear matters. On a clear September evening the views over Trondheim make it one of the better placed festival arenas in Norway.

Festningen has been running as an annual festival at Kristiansten Festning for several years and has grown into what organisers describe as Central Norway's largest music festival. The September slot means the crowd tends to be festival-experienced and the weather is usually mild but unpredictable: prepare for sun and for cold. The fortress setting gives the event a distinct feel that is hard to replicate at a flat park site.

The 2026 lineup

The 2026 headliners are DJ Snake and Sigrid. DJ Snake brings his global electronic and hip-hop catalogue; Sigrid is one of Norway's biggest pop exports and performs at Festningen as a homecoming of sorts. The full lineup, per the official festival website:

• DJ Snake
• Sigrid
• Marcus og Martinus
• TIX
• Musti
• Bausa
• Donkeyboy
• Soppgirobygget
• Erik og Kriss
• Ari Bajgora
• Undergrunn
• Tobias Sten
• Synne Vo
• Søte og Rare
• Zimmermann

The programme spans pop, hip-hop, and electronic, with a mix of Norwegian acts and international names. Day-by-day scheduling is published on festningen.no when confirmed. Artist cancellations can happen without triggering a ticket refund; check the ticket terms at purchase.

DJ Snake is one of the biggest names in global electronic and hip-hop production, known for hits that cross genres and audiences. Sigrid brings her indie pop and stadium pop back to a Norwegian stage. Marcus og Martinus, Donkeyboy, and TIX anchor the Norwegian pop side of the bill. The mix of established Norwegian names and international headliners has become a characteristic of Festningen's programme over recent years.

Getting to Kristiansten Festning

The fortress is the most accessible part of the whole weekend to plan. Walk there from anywhere in the Trondheim city centre and you will arrive in fifteen to twenty minutes. Local city buses serve the area; night buses run back toward the centre until late on both festival nights.

If you are flying in, Trondheim Airport Værnes is approximately 32km from the venue, around 32 minutes by road. A bus runs from the airport to Trondheim Central Station (Trondheim S), from where you can walk or catch a local bus to the fortress. Taxis and rideshare are available from both the airport and the city centre. Source: Festival Abroad planning guide.

No dedicated festival shuttle is listed for 2026. Check the festival's channels at festningen.no for any transport updates in the weeks before the event.

What to bring, what to leave at home

The following items are not allowed inside Festningen, per the official rules:

• Glass and bottles
• Umbrellas
• Weapons or any object that can cause injury
• Animals
• Outside food and drinks (not permitted for safety reasons)

Bring with you:

• Valid photo ID
• Your ticket (phone or printed)
• A payment card; the festival operates cashlessly
• Layers: September evenings on a Trondheim hilltop can get cold after dark
• Comfortable, sturdy footwear for uneven terrain and cobblestones
• Sunscreen for the afternoon if it is a clear day
• A charged phone

Photography and video recording happen throughout the site for the festival's own marketing; by attending you consent to appearing in that material.

Food and drink on site

Because outside food and drinks are not allowed, you rely on what the festival provides. Festningen runs food and drink stalls throughout the site with vegetarian and gluten-free options available alongside the standard menu. Source: festningen.no/info. Check the festival's website for the full vendor list closer to the event.

Lockers

Locker hire is available at Festningen through the festival's own service, listed as Lei skap on the official website. Renting a locker means your bag, jacket, and valuables stay secure while you move freely between stages. Check availability and book at festningen.no closer to the event.

Accessibility

The full Festningen site is wheelchair accessible. A dedicated platform with clear sightlines to both stages is reserved for festival goers with accessibility needs. Companions using the companion scheme do not pay separately but must collect a day wristband from the accreditation booth on arrival. For specific accessibility questions, contact the festival directly at hei@festningen.no. Source: festningen.no/info.

Where to stay

There is no camping at Festningen. The city centre is your best base: the venue is walkable from most hotels in central Trondheim, which means you avoid any transport stress at the end of the night.

Hotels within walking distance of the fortress include Hotel Britannia and Clarion Hotel Trondheim in the centre. Trondheim Vandrerhjem hostel is around fifteen minutes' walk from the fortress and is a lower-cost option. September is busy in Trondheim; book early. Source: Festival Abroad planning guide.

On the day: what to expect

Doors open at 15:30 on both days. Arriving at opening is a good way to avoid queues at the entrance and get your bearings before the main acts start. The accreditation booth is outside the festival area, so if you are using a companion pass, head there first before going through the main gate.

Payment across the site is cashless, so a working card is essential. If your phone is your ticket, make sure it is charged before you arrive; the fortress setting means there are no convenient wall sockets. Keep your bag light and within the permitted size so entry is fast.

Lost property during the festival goes to the info booth on site. After the event closes, lost items are transferred to the local police. Contact the festival at hei@festningen.no for anything you are missing.

Waste and sustainability

Festningen sorts waste on site across multiple streams including cardboard, general waste, and food waste. Separate bins are placed throughout the grounds. Source: festningen.no/info.
