The Bochnia Salt Mine () in Bochnia, Poland, is one of the oldest salt mines in the world and is the oldest commercial company in Poland. The Bochnia salt mine was established in 1248 after salt had been discovered there in the 12th and 13th centuries, and became part of the royal mining company, Żupy krakowskie (Kraków Salt Works). In 1990, the mine ceased producing salt but remains a tourist attraction. Read more on Wikipedia
