Wieliczka Salt Mine

The Wieliczka Salt Mine, near the Polish city of Krakow, is a salt mine that has been in continuous operation since the 13th century, and still is producing table salt today. The mine stretches to a depth of 327 meters and is more than 300 km long.  In addition to its purpose as a mine, Wieliczka features a oturist route lined with statues of historical and mythical figures (all of them sculptured out of salt by miners), chambers and chapels lined with salt crystal chandeliers, underground lakes, and exhibits showing the history of salt-mining.
