Bornholm's Defense Museum

Visit the interesting Museum of Defence - Bornholms Forsvarsmuseum - in Rønne.

A unique collection

The museum displays a unique collection of historical artefacts from the island’s military history ranging from the 17th century to the present day.

A large part of the museum is focused on the history of the local Danish military units, but the museum’s exhibition on the Second World War includes leftovers from the German and Soviet occupations – incl. weapons, uniforms and a German Enigma encryption device (know from such films as ‘The Imitation Game’ and ‘U-571’).

Kastelstårnet – an impressive tower

Near the Museum of Defence, a bit south of the old part of Rønne, you will also find the impressive tower Kastelstårnet with its round shape and its four metre thick walls. This tower looks like the round churches of Bornholm, which were built 4-500 years earlier.
