Via Kuriositas:

Deep underground in Poland lies something remarkable but little known outside Eastern Europe. For centuries, miners have extracted salt there, but left behind things quite startling and unique. Take a look at the most unusual salt mine in the world.

From the outside, Wieliczka Salt Mine doesn’t look extraordinary. It looks extremely well kept for a place that hasn’t minded any salt for over ten years but apart from that it looks ordinary. However, over two hundred meters below ground it holds an astonishing secret. This is the salt mine that became an art gallery, cathedral and underground lake.

Situated in the Krakow area, Wieliczka is a small town of close to twenty thousand inhabitants. It was founded in the twelfth century by a local Duke to mine the rich deposits of salt that lie beneath. Until 1996 it did just that but the generations of miners did more than just extract. They left behind them a breathtaking record of their time underground in the shape of statues of mythic, historical and religious figures. They even created their own chapels in which to pray. Perhaps their most astonishing legacy is the huge underground cathedral they left behind for posterity.

It may feel like you are in the middle of a Jules Verne adventure as you descend in to the depths of the world. After a one hundred and fifty meter climb down wooden stairs the visitor to the salt mine will see some amazing sites. About the most astounding in terms of its sheer size and audacity is the Chapel of Saint Kinga. The Polish people have for many centuries been devout Catholics and this was more than just a long term hobby to relieve the boredom of being underground. This was an act of worship.

Amazingly, even the chandeliers in the cathedral are made of salt. It was not simply hewn from the ground and then thrown together; however, the process is rather more painstaking for the lighting. After extraction the rock salt was first of all dissolved. It was then reconstituted with the impurities taken out so that it achieved a glass-like finish. The chandeliers are what many visitors think the rest of the cavernous mine will be like as they have a picture in their minds of salt as they would sprinkle on their meals! However, the rock salt occurs naturally in different shades of grey (something like you would expect granite to look like).

Still, that doesn’t stop well over one million visitors (mainly from Poland and its eastern European neighbors) from visiting the mine to see, amongst other things, how salt was mined in the past.

This stunning chapel has to be my favorite:
