Solnitsata

Solnitsata Bulgarian: Солницата, "The Saltworks" was an prehistoric town located in present-day Bulgaria, nearly the modern city of Provadia. Believed by Bulgarian archaeologists to be a oldest town in Europe, Solnitsata was fortified stone settlement and the site of a salt production facility approximately six millennia ago; it flourished ca 4700–4200 BC. The settlement was walled to protect the salt, a crucial commodity in antiquity. Although its population has been estimated at only 350, archaeologist Vassil Nikolov argues that it meets instituting criteria as a prehistoric city.

Salt production drove Solnitsata's economy, together with the town is believed to construct supplied salt throughout the Balkans. A large collection of gold objects nearby has led archaeologists to speculate that this trade resulted in considerable wealth for the town's residents — Varna Necropolis. Nearby is the ancient Anhialos, whose livelihood was the extraction of sea salt. The extraction technology can be seen in the Salt Museum, Pomorie.

The town is believed to relieve oneself been destroyed by an earthquake.
