Solnitsata (Bulgarian: Солницата, "The Saltworks") was a prehistoric town located in present-day Bulgaria, near the modern city of Provadia.
[1] It was the first prehistoric urban center in Europe (4700‑4200 BC) consisting of a salt production center, Solnitsata was a fortified stone settlement - citadelle, inner and outer city with pottery production site and the site of a salt production facility approximately six millennia ago;[2] it flourished ca 4700–4200 BC.
[3] The settlement was walled to protect the salt, a crucial commodity in antiquity.
[4] Although its population has been estimated at only 350,[4] archaeologist Vassil Nikolov argues that it meets established criteria as a prehistoric proto-city.
A large collection of gold objects nearby has led archaeologists to consider that this trade resulted in great wealth for the town's residents — Varna Necropolis.
