Gradishte, Thracian megalithic sanctuary in Dolno Dryanovo, Bulgaria.

Gradishte is a rock-cut sanctuary near Dolno Dryanovo, on the road to Satovcha, covering about 20 decares of rock formations up to 88 m high within a 500-decare complex. Its megalithic ensemble includes anthropomorphic and zoomorphic figures, among them giant stones named "Tangra 1, 2 and 3" by Prof. Todor Boyadzhiev, and a stone arch used in healing rites.

The sanctuary was discovered by Polish archaeologist Prof. Mieczysław Domaradzki during fieldwork in the late 1980s. In 2000 Prof. Todor Boyadzhiev came upon it again by chance when he stopped at a roadside turnoff on the road from Gotse Delchev to Smolyan. Rescue excavations in April 2008, led by Anelia Bozhkova and Nadezhda Todorova, covered 150 m² and found Late Iron Age pottery, loom weights and roof tiles.

Walking through the sanctuary, you see carved circles and ritual steps cut into stone, with a ceremonial arch that locals call Promushvalka where people once gathered for healing practices.

The sanctuary lies 5 km from Dolno Dryanovo on the road to Satovcha, in the Gradishte area. The rock complex covers about 20 decares within a 500-decare site, with rocks up to 88 m high. Two unstudied cave shelters and remains of a Roman road at the foot of the Dabrash ridge are nearby. The terrain is rocky and unmarked.

The rocks of the sanctuary rise up to 88 m, but they are not a summit: the cult complex covers about 20 decares within a 500-decare rock area. Two cave shelters inside the site remain unexcavated, and remains of a Roman road lie at the foot of the Dabrash ridge.
