Theta Museum in Bergen is a museum that focuses on the resistance movement during World War II, with a particular emphasis on the Theta Group. This group was established in 1940 and consisted of young people aged 19 to 22. The museum presents the story of how the group worked to maintain radio contact between the Norwegian authorities in England and the resistance movement in Norway, as well as the challenges they faced in this process.
The headquarters of the Theta Group was located in Enhjørningsgården on Bryggen in Bergen. The group prioritized obtaining information about German naval movements, which was critical for the Norwegian resistance movement. The museum also highlights events that led to the group being temporarily stopped, including the arrest of a member and the subsequent raid by the Germans on Bryggen. Through exhibitions and information materials, Theta Museum provides insight into an important part of Norwegian history.
