The Soledar Salt Mines

Some 250 million years ago, a part of Ukraine was under a shallow ocean. When the ocean dried up, it left behind a huge deposit of salt which got buried underneath due to upheavals in the earth’s crust. A large concentration of this salt is located under a small city called Soledar, a Russian word meaning “gift of salt”.

For a long time, this area was known for brine springs, caused by the solution of underground salt deposits by ground water. This brine was used to produce salt since the 16th century. The brine was cooked in pans with wood fires, to evaporate the water. This process was extremely energy hungry, leading to large scale deforestation in the regions south of Soledar. In the 18th century, … Read the rest
