Wieliczka is a town near the city of Kracow in Poland. But another city lies directly under Wieliczka, a “city of salt.”
Beneath Wieliczka is one of the world’s largest salt mines. It has been producing salt since medieval times. The mines are on seven levels, the deepest of which is 1,000 feet below the surface. The mines contain about 75 miles of passageways and chambers, plus 16 lakes!
Visitors to the “city of salt” can also see chapels, shrines, monuments, chandeliers, doorways, and other structures, all carved from crystal rock salt!
