Poland’s 700-year old salt mine, just outside Kraków, not only is a cultural art treasure, but also an active research site for geologists, chemists and more.
Water and pollution threaten Poland’s 700-year-old World Heritage Site.
WIELICZKA, Poland — Shining a flashlight, Marek Klimowicz [KLEE-moh-veech] leads me through a dimly lit tunnel. Old wooden timbers support the roof and walls of rock. The tunnel leads us to a warren of rooms large and small. With few exceptions, Klimowicz says, “Everything here is salt.”
There’s salt above us. We walk on a floor of salt. Just an arm’s length away are walls of salt. In all, this underground warren contains some 2,000 chambers. They span a vast 7 million cubic meters (265 million cubic feet). That’s nearly triple the volume inside the Great Pyramid of Giza in Egypt.
