These Incredible Salt Mines Are Like Another World Beneath Our Feet

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.
