ARCHAEOLOGICAL EXPLORATIONS NEAR TVARDITSA (Krasimir Velkov – dakras@abv.bg, Tatyana Kancheva–Ruseva) The enclosure constructed of roughly-cut stones and boulders, 13.50 m in diameter, was thoroughly explored in the southeastern quarter of the tumular embankment. Eight burials were discovered: one cremation and seven inhumations. Thus the total number of the burials discovered in the tumulus so far reached 113. The dead buried in Grave No. 113 was a man, 20 – 40 years old, laid in a Hocker position on his right side with head to the south. The burial probably dated to the Early Bronze Age. The cremation in Grave No. 111 was carried out outside the burial pit, which measured 1.20 m by 0.90 cm, 20 cm in depth. The burial dated to the 3rd century AD. The other six inhumation burials had features, similar to the burials discovered during the previous excavations. An adult was buried in Grave No. 107 and a child was buried in Grave No. 110. The dead were laid supine with heads to the west. The inhumation burials dated to the 4th – 5th centuries AD.
