It is dedicated to 20 years of archaeological research of the oldest prehistoric salt mining and urban center Provadia-Solnitsa and 155 years of the Bulgarian Academy of Sciences, the museum team noted.

According to scientists, the emergence of the Saltworks near the town of Provadia in antiquity is associated with the largest and only deposit of rock salt in this part of the Balkan Peninsula. In the 5th millennium BC, the area managed to establish itself as a leading economic factor on the Old Continent. The Provadian salt "ingots", used as a monetary equivalent, reached distant lands, providing the local population with wealth and a prosperous life.
