Tomb of Seuthes
The most famous tomb-temple in the Valley of the Thracian Kings is that of King Seuthes III, located near the village of Shipka and known as Kosmatka. The site remained sealed for 2,300 years and was discovered by Bulgarian archaeologist Georgi Kitov only in the early 2000s. A treasure reminiscent of that of Tutankhamun was uncovered inside, but no bones were found—indicating that the “tomb” was likely not a burial site, but rather an initiation temple or a spiritual place commemorating the king.
It is an artificial mound supported by a retaining wall, with a diameter of 150 meters. To its south lies a worship platform, likely used for Orphic dances and music. A long corridor shaped like a tomb leads to a central round chamber, from which one exits into a large sarcophagus-like room to the north (again, no human remains were found). At the entrance to the “tomb” was found a cast of the face of King Seuthes—a kind of funerary mask, possibly intended as a warning to those who dared to enter. The figure was identified by coins from the period bearing the name Seuthes and a face resembling the one on the mask.
In the central circular room of the “tomb,” there is a unique acoustic effect—likely accompanied by an energetic one—arising from the dimensions and materials of the space. The diameter of the room is 3.60 meters, which is twice the estimated height of the king, or equal to the extent of his energy field (aura), which reaches to the fingertips when the arms are outstretched. The walls are built of basalt stones brought from afar. The space likely served as an initiation chamber, intended to intensify the thoughts and emotions of those who entered, and to enable contact with the spiritual world—symbolically allowing death, rebirth, and connection with the inner divine light that empowered the king to rule in a sacred manner. A ray of sunlight entered the inner room on a specific day of the year, symbolizing the union of masculine and feminine energies.
In the adjacent sarcophagus room, treasures were discovered: a gold crown made of crumpled oak leaves (symbolizing death), kneepads bearing the image of Hermes (guide to the afterlife), and other ritual objects meant to assist in spiritual rebirth, such as silver wine goblets. These treasures are now displayed in the municipal museum in Kazanlak.
Seuthes ruled parts of ancient Thrace that were liberated from Macedonian rule following the death of Alexander the Great, during the late 3rd to early 2nd century BCE. He led a revival of Thracian worship and culture while simultaneously embracing elements of Greek civilization. This was expressed in the founding of the first Thracian city built according to the Hippodamian grid plan—named after him, Seuthopolis—in which Greek inscriptions were found. The city was a center of temples devoted to the Great Gods from the sacred sanctuary on the island of Samothrace. Seuthes was a priest-king who promoted the cult of Dionysus Sabazios.
