This was originally a stone quarry from the turn of the last century, this extensive underground space was also home to a NATO bunker. The bunker is stripped out, but it is not too hard to work out what was going on down there. Tanks and armored cars in almost mind condition are still down there. It took me several attempts to get inside this quarry the first time dogs yes dogs! where chasing me in this quarry in complete darkness I never run that fast in my life.
