Fort Høytorp, Military fort in Indre Østfold Municipality, Norway
The fort contains an extensive network of tunnels, rooms carved into rock, and defensive structures surrounded by a 1580-meter barbed wire barrier.
Built between 1912 and 1918, Fort Høytorp engaged in combat with German forces in April 1940, serving as Norway's main inland fortress during World War II.
The fortress features three restored tower cannons, including a functional 12 cm Schneider cannon that represents Norwegian military engineering from the early 1900s.
Visitors can explore the fort through guided tours during summer months, walking through underground passages and reaching observation points at the mountain facility.
The main installation, Reduiten, became Norway's largest concrete building upon completion, containing military quarters, ammunition rooms, and two 12 cm turret batteries.
