A unique historical collection
The museum’s collection offers many unique and interesting objects that make it a must-see attraction for anyone with an interest in military history. Below are three featured historical objects that are part of the permanent displays at the museum.
Museum highlights
Germany's wartime secret - The Enigma-machine
See the museum’s German Enigma encryption machine from the Second World War. There are only 284 machines left that were used during the war. The museum’s Enigma was discarded in a ditch at the end of the war, when the German troops on the island surrendered to Soviet forces.
Debris from a V-1 'buzzbomb' crash
In 2021 the museum opens a new exhibition about the V-1 flying bomb that crashed on Bornholm during the Second World War. Danish resistance smuggled intel about this new weapon to the Allies as an early warning about what was to come – but it had dire consequences.
A Danish war hero's sabre from 1864
Sabre from the Danish war hero Lieutenant Anker who served in the 1864 Second Schleswig War against Prussia and Austria. Anker was born on Bornholm and served the first part of his military career in the island’s militia.
Visit a 300 year old fortress
The ‘Kastellet’ (English: Citadel) is part of Rønne town’s fortification. Build by order of the Danish King Christian IV during the period of 1679-1684. The citadel is 10 meters in height and is protected by 3½ meter thick walls. Although it resembles Bornholm’s round churches in design, the design is borrowed from Mediterranean fortress types. During its 300 years it has been both a fortress, a plaque quarantine area and a radio station.
