Trips to Auschwits and Wieliczka"The historic Salt Mine in Wieliczka is the only site in the world where mining has 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 the total of 300 kilometres: reaching the depth of 327 metres they illustrate all the stages of the development of the mining technology over time."
