The Wieliczka Salt Mine (Polish: Kopalnia soli Wieliczka) is a salt mine in the town of Wieliczka, near Kraków in southern Poland. From Neolithic times, sodium chloride (table salt) was produced there from the upwelling brine. The Wieliczka salt mine, excavated from the 13th century, produced table salt continuously until 2007, as one of the world's oldest operating salt mines. Throughout its history, the royal salt mine was operated by the Żupy Krakowskie (Kraków Salt Mines) company. Due to falling salt prices and mine flooding, commercial salt mining was discontinued in 1996. More information...
