Out in the dense forests, an abandoned army depot was found, probably originating from WWII or the early days of the cold war. It is thoroughly camouflaged and well integrated into the rock, most likely to be able to survive a hit with nuclear weapons. Extensive amount of equipment, probably state-of-art during the 1950's seems to have been installed to keep the moisture away. It seems like the storage was abandoned some twenty years ago or so, and dripping water and a dense dampness eats up all metal parts by corrosion and the concrete cracks up.
It must have been "quite sought after goods" inside, as a large number of massive steel doors needs to be passed in order to get into the interiors of the depot. It is of course a large curiosity to think about what could have been stored there...
