Tatul and Perperikon, The Rhodope Mountains

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.
The medieval archaeological complex Perperikon near Kardjali is one of the most ancient monumental megalithic structures, entirely carved into the rocks. It is one of the most popular tourist destinations in Bulgaria.

Religious activity at the top of the cliff began in the 5th century BC. It is associated with the beliefs of the Copper Age people, who started the cult of the sun god. Here they established the first sanctuary and started leaving food containers for the gods.
