Solni Trg — Salt Square — is an open-air museum in the heart of Tuzla's old town, occupying the site of one of the city's historic salt-production areas. The exhibition tells the story of salt extraction in Tuzla from the Neolithic period through the Ottoman era, Austro-Hungarian industrialisation, and into the 20th century.
The square itself has been redesigned to incorporate archaeological finds and historical equipment. A preserved section of the ancient brine extraction system, reconstructed salt-production vessels, and explanatory panels walk you through the industry that has defined the city since prehistory. It's a good complement to the Pannonica Lakes — the two together explain both the history and the consequences of Tuzla's relationship with salt.
