Rocky sanctuary "Harman Kaya", village of Bivolyane
The sanctuary Harman kaya is located in the neighbourhood of the same name, around 2 km North-Eastern from the village of Bivolyane. This is a sanctuary hewn into the rocks situated around a small cave and raising above a river valley, over a fortified by the rocks plateau. The early archaeological heapings of rocky fragments date to the late Eneolithic Age. Around the whole surface could be seen hewn into the rock facilities – premises, round and trapezium-shaped niches, sepulchres, cisterns, concentric circles looking like a sand-glass, sacrificial altars, pools, steps. The internal sacred space was accessed through a crevice between the rocks, additionally processes as entrance and closed by a door – the traces of the threshold and grooves remained even to this day. In the area of the external sacred space are situated numerous sacrificial pits, , altars, pools and bases of dwellings. On the rocks raising around could be seen hewn out beds for wooden constructions, as well as trapezium-shaped niches and altars for sacrifices. In the foots of Karman kaya could be also seen the thousands of years old remains of a Thracian city – remains of streets and squares, of water reservoirs. Still unexplored and unknown for most of the tourists, Harman kaya fascinates with beauty and influence over the human’s mystic conception of the world.
