Kopalnia soli

An abandoned salt mine in Poland. I visited it during trip in 2013.
The mine until 1977 was the largest salt mine in Poland, then this name was taken over and still has a salt mine in Kłodawa.
The mine was closed as a result of the catastrophe – the penetrating water in increasing quantities caused the leaching of salt and the collapse of the corridors.
