The temple dates back to the middle of the IV century BC. It is divided into six parts. In the square southwest chamber a horse had been offered as a sacrifice. The ceiling of the tomb is impressive with its sectional structure and the unique image of the face of a beautiful woman. The central chamber is carved out of a single granite block weighing about 60 tones.
The burial complex was discovered on March 13, 1993 near the town of Shipka and is considered a unique archaeological discovery. It is divided into six rooms with Thracian cups, amphorae and other architectural details placed in rows in front of them. The southern entrance leads to the central “distributing” room with three entrances for the chambers to each side and to the north. The right-side room is circular and dome-shaped. The others are built of cut granite blocks with double-slope cover. The southwest chamber is rectangular and has not been looted. A horse sacrifice has been carried out in it and some metal ritual objects were also found on the spot. Ornaments of horse harnesses were also found in this chamber- a head-protector shaped as a double axe with a three-dimensional head of a griffon and six silver cheek-protectors. All objects have rich decoration of animal and floral motifs. Deformed silver phial and small jug were found as well. The monolithic sarcophagus-like burial chamber, the walls of which were very well treated from the outside and inside, is elevated, with three steps. It is attached to the base by means of a compact lead grouting. The chamber itself is carved out of a single monolith granite block that weighs about 40 tones and is taken from a stone-pit in the northern slopes of the Sredna Gora Mountain. Next to the northern wall there is a bed with vertical belts shaped as legs, as well as a horizontal belt. A step which ends with lion paws decoration leads up to the bed.
The burial chamber is covered with a 20-tonne double-slope roof from a monolith granite block. Its two frontons and the cornice are covered with fine white plaster, which resembles marble. The roof of the chamber is formed in a very interesting way – in the middle there is a big circle, the solar disk, outlined by two intertwining squares, and 38 square cassettes are located around them in all directions. The ceiling is covered with mural paintings and the details of some of them are accentuated with gold. From the preserved paintings it can be judged that the cassettes had contained portraits, fragments, mythological and everyday scenes. The best preserved painting is a miniature portrait of a woman with short brown hair, golden earrings and a golden necklace. The portrait is strikingly beautiful and expressive. Regretfully, around the IV century AD the burial complex was plundered by the early Christians and most of the paintings were destroyed as they were considered pagan.
