Top secret cold war coastal artillery fortress museum - naval artillery bunker.
Built into the rock below Oxelosund in Sweden is a huge nuclear safe bunker, from which 70 soldiers could defend this part of Sweden with 3 guns against an invasion from the Soviet Union and the Warzaw Pact during the cold war. You can visit the guns both above and below ground. Over 450 meters of tunnel system links the different parts within the fortress, which is protected by 10-30 meters of granite and concrete.
The fortress is open with guided one hour tours daily in summer season and weekends during spring and autumn. Groups are welcome all year round. There is a small café and museum shop with souvenirs and cold war books at the fortress. Information:
Tankspotting (TV) is dedicated for the heavy metal battlefield. If you enjoy tanks and other awesome things then please subscribe - just click here:

Shown in the video are Värnkanon m/74. The Värnkanon at Ljungholmen was in place from the 1970s until the end of the 1990s and was tasked with defending the entrance to Oxelösund harbor and the mining at Ljungholmen.
Facts: The m/74 defensive gun had a caliber of 7.5 cm and consisted of the turret from decommissioned tanks of the Stridsvagn 74 tank.
As part of the self-defense of the Femöre Battery (Femöre Fort), so-called dummy targets were included in the war organization, including two dummy guns and a dummy radar.
The intention of these was to trick an attacker into attacking the dummy targets instead of the real ones.
The dummy pieces would be placed so that they were visible from the sea, while the sharp pieces would be camouflaged as much as possible.
The tracking radar was placed visibly at the Lighthouse Residence, while the sharp radar was to be used inside the weather shelter and camouflaged with netting.
