Hegra Fortress
Hegra Fortress is a national heritage site and a powerful symbol of Norwegian resistance. Here, you can explore a unique military installation with trenches, tunnels, and historic buildings, all set in the beautiful Trøndelag landscape.
The fortress is especially known for the dramatic battles of 1940, when a small Norwegian force held out against German attacks for 25 days.
Today, visitors can explore the site on their own, join a guided tour, visit the museum, and enjoy a break in the café.

The Museum at Hegra Fortress
The museum at Hegra Fortress is housed in a reconstruction of the original 1917 depot building, which was destroyed during the war.
The exhibitions tell the story of the fortress's construction, its role in neutrality guard duty during World War I, the battles of 1940, and the restoration efforts in the 1980s.
Visitors can view photographs, uniforms, weapons, and personal artifacts from the period.
The museum and café are open from mid-May to early October, Wednesday to Sunday, 11:00–16:00.
Guided tours are available Sundays at 13:00, and can also be booked for groups.
History of the Fortress
Hegra Fortress, formerly known as Ingstadkleiva Fort, was constructed between 1908 and 1910 as part of Norway’s defense strategy following the dissolution of the union with Sweden.
Built into the mountainside, the fortress includes trenches, tunnels, a command post, and gun emplacements, and was designed to defend the Trøndelag region from a potential attack from the east.
The fortress remained operational until 1926, after which it was maintained in a state of readiness.
During the German invasion of Norway in April 1940, Hegra Fortress was reactivated by Major Hans Reidar Holtermann. Around 250 volunteers—both soldiers and civilians, including one woman—manned the site.
For 25 days, they defended the fortress against superior German forces in what became known as the Battle of Hegra. Although the military impact was limited, the resistance carried great symbolic value, representing Norway’s will to defend and remarkable endurance.
After the war, the fortress was restored and developed into a museum and cultural heritage site. In 2025, Hegra Fortress was officially protected by the Directorate for Cultural Heritage (Riksantikvaren).
Today, the site is open to the public, featuring trenches, mountain installations, a museum, and a café. It stands as a living symbol of resilience, set in scenic surroundings ideal for day trips and historical experiences.
