During WWII a lot of gunpowder was needed so the Swedish government decided to build a secret plant with over thirty buildings in the forests of Dalarna. The Gunpowder factory at Tyfors was built in 1940 and in operation until 1945 but the military didn’t completely abandon it until 1978. Since then Mother Nature is reclaiming its area slowly, even though it has passed lots of years most of the buildings still stand there.
