The Thracian sanctuary near Tatul Village, Momchilgrad Municipality, is one of the most imposing megalithic monuments discovered on the territory of Bulgaria. It lies just 200 m away from the village and approximately 15 km away from Momchilgrad.
The sanctuary is a massive rock structure and its top is a truncated pyramid. The complex comprises two sarcophagi, a rectangular bed for the main altar, and a three-metre-deep well. It dates back to the end of the 5th and the beginning of the 4th centuries BC. Evidence to that is provided by the clay vessels that were discovered in the region.
