The Tatul tomb is situated just outside the present-day village of Tatul, 8km to northeast of the town of Momchilgrad. The sanctuary lies inside the fortress walls of a Thracian fortress and is believed to have been dedicated to the famous Thracian singer, Orpheus. The sanctuary, deemed to date back to the 12th century BC, represents a big monolithic rock shaped by men into a pyramid. It is 4.5m high and 6m wide at its base. Within its body, worshippers have dug two rocky cemeteries, 8 stairs, and a niche for laying a ritual plate.
