Salt mine - Wieliczka
Wieliczka Salt Mine is a place for those who not only love to visit caves and mysterious caves, but also for those who like to listen to interesting stories, enhanced by echoes. Sold out in the salt chamber, amazing structures and captivating underground lakes are not all that make up the magic of Wieliczka.
Absolutely stunning. I went there a few years ago and even though these pictures are beautiful, they don't do it justice
