Archaeologists have uncovered an ancient Thracian town in Karlovo Municipality in Central Bulgaria, local media reported on Sunday.
Initial estimates dated it to the 5th century B.C., and remnants of the town's fortress wall have been unearthed.
The archaeologist will be looking for the residence of the ruler, supposed to have been a powerful Thracian king, reports said.
Greek vessels, most probably used to keep wine, have also been found.
Reports said that the ancient Thracian town may prove to be one of the most important sites in the history of Bulgarian archaeology and to provide valuable information about the life of Thracians in the region.
