Belintash (pronounced as "Belantash" and "Belǎntash" in some local Bulgarian dialects) is a small plateau in the Rhodopes Mountains ( Bulgaria) bearing traces of human activity. It is assumed that this is a cult site of the ancient Thracian, though the very essence and purpose are not yet fully understood. There are also suggestions that the sanctuary was dedicated to the god Sabazios ( Ancient Greek: Σαβάζιος) built and operated by the independent Thracian tribe Bessi. The upper platform of the plateau is marked with carved round holes, trails, niches and steps that some researches interpret as stellar map. It is claimed by some Bulgarian media that in 2006, anonymous tourists had discovered the so-called "Inscription of Belintash" - a petroglyph carved into the rocks, which according to some theorists, confirm that the Thracians had their own alphabet that pre-dates Greek alphabet. (Authenticity of the petroglyph has not yet been confirmed or denied by archaeologists working on the site of Belintash.)
