Sanctuaries in Eastern Rhodope mountains are 1 000 years older than the Egyptian Pyramids and the Mesopotamy's civilization, believe Ana Raduncheva and Stefanka Ivanova, archaeologists.

According to their statement the sanctuary system in the Rhodope had been created in the 5 c.B.C. which means almost 4 000 years before the Thracian to come and settle down in the Bulgarian lands.

At the end of the stone-cooper age, the rocky sanctuaries are abandoned and desolate for a long time. They were found again from the Thracian 2 500 years later.
