You might doodle your name in bubble letters whilst on the phone to a client, or stick a colleague's face on Pharlap's body in Photoshop, but the Polish salt miners really knew how to get creative at work.
For centuries, miners at the Wieliczka Salt Mine, near Krakow in southern Poland, chiseled mythic, historical and religious figures out of rock salt. The reliefs and carved sculptures are acts of worship rather than products of boredom - most miners were devout Catholics. Two hundred metres below you'll find dozens of salty statues, a cathedral, as well as underground lake. The mine hasn't been in operation since 1996, but that doesn't stop millions of people visiting it every year.
