The Hiiumaa Military Museum was established in 2007 in the former border guard station of Tahkuna.
The museum takes pride in its collection of coastal defence cannons – featuring 180 mm, 130 mm and 100 mm cannon barrels. The outdoor exhibition includes armoured personnel carriers BTR-70, BRDM-2, ZIL-157, GAZ-66 and other vehicles, a reconstruction of the border strip, civil defence shelter, border guard speedboat, sea mines, anti-tank gun, border guard viewing platform, radar and radio masts. The diesel house features a fully equipped diesel generator, as well as fuel tanks and canisters. In the museum's main building, the preserved marine observation radar, in use until 2005, still stands in its original place. The museum has held exhibitions of cannon projectiles and shell casings, helmets, hats and uniforms, communication devices, educational posters, and civil defence equipment. It also has a furnished barracks corner with an iron bunk bed, a Communist dedication corner and an armoury.
