Let's have a look at the fascinating history of the salt production, which starts in the ancient times. Then, this article will lead the reader through various attractions and curiosities in the Wieliczka facility.

Start of Salt Production in Wieliczka

Wieliczka is the oldest site of the salt extraction in Europe. In neolithic period, about 4000 b.c., local settlers, who lived off agriculture and cattle breeding, were producing it for trade and use. Initially, people used to draw water from salty springs and evaporate water from the brine to get a pure salt.

Local craft and trade was thriving. In 12th century, papal legate Gilles de Paris confirmed the privilege of a Benedictine Abbey to freely collect the salt, which was produced in Wieliczka, called Magnum Sal in the document.

In 13th century, people started to extract the rock salt from underground mines in Wieliczka. Therefore, first mine shafts, called "Na zamku" and "Goryszowski" became active. A Polish folk legend credits the young queen Kunegunda, who was also known as Kinga, with bringing the rock treasure from Hungary as her dowry, when she arrived to marry the Polish prince Boleslaw.

Legend of Queen Kinga's Rock Salt Mine Dowry

The king of Hungary wished to give all the best of his kingdom to his beloved daughter, Kunegunda, who was leaving her homeland to marry the Polish prince, Boleslaw.

However, the demure girl refused gifts of gold, silver and precious jewels. She knew, that merchants  from Poland traded for Hungarian rock salt, because very little of it was excavated in their country. Therefore, a clever princess asked her father for a salt mine as her dowry.

The Hungarian king agreed, yet he was perplexed. How was she going to transport a mining facility? Kinga visited the mine in Prald and threw her engagement ring into the deepest shaft. Then, she travelled to Poland to marry Boleslaw.

The royal pair went to Wieliczka, where the queen ordered workers to dig out a deep shaft in the center of the city. However, the rock layer soon blocked the excavation progress.

The young wife asked for a sample from a rock. Surprised miners noticed, that the pebble was from a pure salt. When first chunk was split open, the missing ring fell out from the inside! Yes, this was the same engagement ring, which Kinga had thrown into a Hungarian mine shaft [2].

History of Underground Salt Mining in Wieliczka

The Saltworks Castle, constructed in Wieliczka at that period, remained serving as the headquarters of mine's management till 1945. After the 2nd world war it became the Museum of Saltworks.

The revenue, which came from the salt works, paid for teaching professorial staff at the Kraków University. At the last period of middle ages, the facility produced about 8,000 tons of salt every year, while employing 350 workers.

During the Renaissance, Wieliczka mines were thriving, increasing their production to 30,000 tons and employing 2,000 workers. Famous people, such as Conrad Celtes and Nikolaus Copernicus, visited mines at least once. At the time of the Swedish invasion of Poland, foreigners accessed mines and occupied them for a brief period.

In 1724, saltworks stopped the processing of brine. Since then, only rock salt has been mined in Wieliczka. In 1772, Austrian army occupied and managed mines, controlling production in Wieliczka and nearby Bochnia.

In 1838, modern saline baths were constructed in Wieliczka. Thriving balneology procedures and clever treatments attracted sick and rich to the health resort in the city.

In 1866, a major flood submerged a whole level six of mines. The damage control worked only after a few years of constant battling with these encroaching waters. To express its gratitude, after conquering the flood, the management founded the Chapel of the Holy Cross, which is located underground in the mine. In 1898, explorers discovered the amazing Lower Crystal Grotto.

Mines remained operational during the brief period of the Polish independence and under the German occupation. After the war, the production was streamlined with modern equipment, even as an employment declined.

In 1964, an Allergy Treatment Health Resort, located underground in the salt mines, opened its door for sufferers. This facility was the first of its kind in the world. In 1966, the Saltworks Museum was opened underground. In 1992, a major flood of water mixed with sand threatened not only mines, but the town as well. The fight for control lasted two years, but ended successfully.

In 1996, the facility ceased to excavate salt, producing it only by evaporation of the flood water. Wieliczka mines became a major tourist attraction in the Kraków area, with over a million visitors each year. To take an advantage of the multitudes, the management has reconstructed old saline baths and built a luxury hotel "Magnum Sal".
