The Rogozen Thracian Treasure was found in the yard of a house in the village of Rogozen during 1985-1986. It was the discovery of the century. It consists of 165 gold and silver objects, weighing over 20 kilograms, making it the largest Thracian treasure ever found in Bulgaria.
The differences in the styles and techniques used in the production of these objects suggest that they were produced at different times and in different places. The artifacts date from the late 6th century to the first half of the 4th century B.C.
Archaeologists suggest that the treasure belonged to a prominent family in the area, a local Thracian dynasty from the time of the great expansion of Thracian power and culture in the Balkan Peninsula. Some of the objects carry the names of the Odryssian King Cotis, and his son Kersebleptes.
The majority of the treasure is kept in the Historical Museum of Vratsa, and 15 items are kept at the National History Museum in Sofia.
