Wieliczka Salt Mine

The Wieliczka Salt Mine is located on the outskirts of Poland's cultural capital, Krakow. The mine was in operation starting in the 13th century all the way until the year 1996. Nowadays it isn't economical to mine here, so the mine had now become a tourist attraction, and for very good reasons. The mine houses some impressive sculptures made from pure salt. The world's largest underground chapel also exists in the Wieliczka Salt Mine. The mine has multiple levels. I only was able to venture down 135 meters below the Earth's surface, however the deepest point in the mine is 327 meters, or about 1,073 feet. There are about 178 miles worth of tunnels inside this massive quarry of salt.
