A gallery of Wieliczka salt mine
The salt mine of Wieliczka, close to Cracow, is worthily an UNESCO monument. It's long adits and large chambers have sprung up since 13th century up to now. In them, salt-made sculptures, underground chaples, museum expositions, dancing floors, conference halls and even restaurants have arisen. Lots of people use to be here and entrance fee is a bit expensive, but the visit is really worth it.
