Notice the chandeliers are made of salt, and you can see the newer salt crystals growing through the ceiling:









According to Polish legend, when the Polish king sent his envoys to take princess Kinga to Poland to marry a Polish king, her father (the Hungarian king) wanted to show a royal generosity by giving gold and silver from his treasury to the Poles. Kinga asked him to give a salt instead, since Poles did have gold and silver but they did not have much needed salt. The king let Kinga to take as much Hungarian salt as she wanted, but Kinga had a premonition and she just dropped her engagement ring to the mine before going to Poland.

After Kinga's wedding in Krakow she went for a trip to a near by town of Wieliczka and she ordered to dig a well. People who dig the well had to stop because they encountered a hard stone.
She then ordered to lift up a chunk of the stone - it was a pure salt with Kinga's ring inside. In the place where Kinga asked to dig a well - huge deposits of pure salt were found. Therefore she became a patron of salt-miners.

This is a carving showing them finding her ring:
