The remains of the Thracian Centre Halka Bunar were found on a low slant terrace, located in direct proximity north of the karst spring of the same name, in the area of Gorno Belevo village (municipality Bratya Daskalovi). These lands have always been in the centre of the political territory of Odrysian State. They belong to the triangle formed by the well-known Odrysian towns Philippopolis - to the west, Seuthopolis - to the north, and the hypothetical Beroe - to the east.
