The reason for these long since planned excavations is the suggestion that life there has inevitably been connected with salt production in prehistory. The preliminary results confirmed this hypothesis. Most probably, a Karanovo III-IV community from Thrace has crossed the Eastern Stara Planina range, and had taken up with salt production through salty spring water evaporation. This Thracian “colony” probably has been exclusively engaged in these activities, and exchanged salt for foods and other products with the “metropolis”. Quite probable is also the relation of the wealth of the Varna cemetery and the salt production at Tell Provadia-Solnitsata in the first phase of Varna culture.
