The favourable geographic and climatic conditions of the territory around Stara Zagora contributed to the establishment of several prehistoric settlements in the remote past. More than 100 prehistoric mounds from the 6th to 3rd millennium BC were found in the vicinity of Stara Zagora. One of them, the Bereketska mound, is the largest in Bulgaria, containing traces of people that lived there from the New Stone Age (6th millennium BC) to the Middle Ages (12th century). A prehistoric settlement can be found within the city itself. Two dwellings from the New Stone Age are preserved in the Neolithic Dwellings Museum. These are the best preserved dwellings from the New Stone or Neolithic Age (6th millennium BC) in Europe and contain a rich collection of tools and artefacts. The oldest copper mines in Europe (5th millennium BC) were found 8 km (4.97 mi) east of the city, A considerable amount of copperore was extracted from the 11 mines by the ancient inhabitants of this land who traded with it throughout the continent.
Located at the cross-roads of multiple civilizations, Stara Zagora is an important piece in the European cultural routes mosaic. Inhabited by ancient Thracians, Romans, Ottomans and Bulgarians, this unique city bears the historical imprint of those past civilizations along with many of their historical treasures. Proof of its longevity can be found in the multiple names of the city, each one connected with a different era of its development.
