Hiiumaa Military museum is located in Tahkuna, Hiiumaa. The museum exposition covers Hiiumaa’s coastal defence structures, armaments, and ammunition.

In front of the main building there is a replica of a part of the Soviet border strip – a three meter wide raked sand strip with a barbed wire fence. Behind fence is an entrance to a civil protection shelter.

At the back corner of the yard is a storage lot for machinery. There you can see military vehicles like the ZIL-157, GAZ-69A, UAZ-469 and the LUAZ-967M. Scattered in the yard are armored personnel carriers BTR-70 and BRDM-2 and a coast guard boat. Among the items of the out-door exposition are railway trams used in the construction of the beach batteries, floating mines, aircraft bombs, a torpedo and others. In the backyard of the museum is a reconstructed 45 mm Soviet anti-tank artillery position. Behind the main building are towering radio masts and a radio antenna.

In the main building of the museum is an exhibition in five rooms. Marine observation radars used by the coast guard until 2005 are still at their original spots.
