It is historically most important salt deposit in locality Solivar near Prešov in eastern Slovakia with number of preserved technical monuments connected with extraction of salt.
Salt springs existed there since the Middle Ages. Salt was obtained from them until 1572 when mining started. As the mines were flooded by water in 1752, it was necessary to apply a different and new technology. The mine changed into an underground salt lake and the technology then applied consisted in extracting the salt water in leather sacks to earth surface with the help of a pump driven by animals.
One such pump still exists in the pit Leopold. It is from the 19th century and accessible to public. In Solivar, apart from technical monuments, visitors can also see the former salt store, the cooking room František, and the chapel of St Roch.
