“The historic Wieliczka Salt Mine is the only site in the world where mining have been continued since the Middle Ages. Lying on nine levels, its original excavations (longitudinals, traverses, chambers, lakes, as well as lesser and major shafts) stretch for a total of 300 kilometres reaching the depth of 327 meters and illustrate all the stages of the development of mining technology over time.” – the quotation from September 8th 1978, when Wieliczka Salt Mine, along with 11 other sites from all over the world, joined the UNESCO’s very first World Heritage list. The mine is also notable for its long tradition of tourism. The famous breathtaking site has been visited over the centuries by Nicolaus Copernicus, Johann Wolfgang von Goethe, Alexander von Humboldt, Dimitri Mendeleev, Pope John Paul II, and crowned heads of state, not to mention millions of people from all over the world. The tour includes a visit to the stunning “underground town” with lakes, passages, and the marvellous Chapel of St. Kinga.
