The prehistoric complex of Provadia-Solnitsata is a landmark site of the earliest European civilisation. It displays the remains of the earliest salt-production centre in Europe (5600–4350 BC), which emerged as the first prehistoric urban centre on the continent (4700–4350 BC). It is located near the town of Provadia in north-eastern Bulgaria, and was established and inhabited by the earliest table salt producers in Europe. The site consists of a salt-production centre with ritual pits, an unfortified and later a stone-walled settlement, a ritual field, and cemeteries. It occupies an area of about 30 hectares. Both field and office interdisciplinary research of Provadia-Solnitsata has allowed the extraction of a considerable body of generalising information about the period from the beginning of the Late Neolithic to the end of the Chalcolithic in the area along the lower course of the Provadia river and Varna lakes. Part of this information has been published either in greater detail or more concisely, however small objects or smaller features usually remain in the background. Therefore, in this short article dedicated to the memory of my colleague and friend, Academician Nikola Tasić, I would like to draw attention to several specific phenomena that represent vivid vestiges of the prehistoric past.
