Namely, much of Europe, in the ancient geological past, represented the bottom of the Pannonian Sea. And the last remains of this must have receded from the present surface 10 million years ago. Just below Tuzla this sea left a trace of 350 million tons of salty rock and salt water. Salt water was raining to the surface, people were processing it in so still in the neolith. They later formed wells, which became more and more modern, and salt water became the basis of the chemical industry in modern Tuzla.

On July 18, 2003, local authorities decided to draw a large amount of salt water to the surface, to the previously prepared bottom, so Tuzla is now the only city in Europe that has a salt lake and the only city in the world whose salt lake is at the same time a bathing place and beach in the narrowest historical city center. The salt water of the Pannonian Lake is allegedly and healing.

Tuzla has a great industrial tradition, based on rich salt and coal deposits.
