12 hour underground jaunt in over 40Km of huge abandoned mine works? Sure, why not. In fact, why don’t we just drive in?
This mine produced limestone, but limestone that could take a shine. Like a cheap version of marble. Countless monuments and many notable buildings are made of products mined from this site. Later years saw the facility extracting stone, and processed underground in an a unique underground plant.
Now it sits quietly in the country side, two giant doors in the side of a mountain, concealing the largest adit we’ve ever seen.
