The geographical center of Bulgaria – between the Stara Planina and Sredna Gora mountains – is known as the Rose Valley. For centuries the fragrant Bulgarian rose has been grown there and the attar of roses is extracted fro the production of rose oil. There, 40 years ago, in the town of Kazanluk a small Thracian Tomb was found, with murals which are of exceptional interest in the world’s cultural heritage.
The settlements in the Rose Valley date from ancient times. A Neolithic settlement (5,000 – 4,000 B.C.) was found in the western area of Kazanluk. The excavations revealed that the settlement had existed during the Stone-Copper Age and during the first half of the Bronze Age ( 4,000 – 3,000 B.C.).
