Salt mines are special compared to other underground excavation sites: once they are closed for extraction purposes, they can be opened for visitors, or for storage purposes—all because of their unique microclimate with natural air-conditioning and constant temperature and atmospheric pressure all year.

Our collection has two main goals: to show how beautiful these artificial caves and huge underground chambers once were, and to show some of the most interesting ways these depleted salt mines are being used. Let us know in the comments if you've ever explored one.

These are a few pictures from my trip to Wieliczka.

Underground "river" with Tunnel of Love style ride. It was shut down after some military personnel got carried away and tipped the boat. They were all stuck under the boat and drowned because the water's salinity caused them to be hyper buoyant.

Close up of the chandeliers in the cathedral, made of pure salt.

A statue carved of pure salt, it is a likeness of King Casimir III the Great one of Poland's most beloved kings.

And just a picture of some artwork carved into the salt walls of the cathedral.

It really was a great trip, I highly recommend that if you find yourself with a spare afternoon in Krakow go ahead and hop on a bus and take the tour, its really something.
