The Wonders of the Wieliczka Salt Mine

Wieliczka Salt Mine

Deep under the earth, 14km south of Krakow, the Wieliczka salt mine is one of the wonders of Poland. Dating back to the Middle Ages, this subterranean labyrinth of tunnels and chambers has morphed from an industrial plant at the heart of the Polish economy, into a world-famous tourist attraction, event location and a health resort. Read on to discover 10 fascinating facts about this UNESCO World heritage site.

1. Approximately 7.5 million cubic metres of salt deposits have been extracted from the mine over the past seven centuries. That's enough to build three Great Pyramids of Giza.

2. The Wieliczka Mine has nine levels and reaches down to a depth of 327 metres - deep enough to hide the Eiffel Tower.

4. In the Renaissance, income from the mine and the sale of salt constituted a third of the state treasury's income.

8. The Stanislaw Staszic Chamber is an awe-inspiring 36m high - tall enough to accommodate Poland's tallest native tree, the Bartek Oak.
