SUMMARY
In 2016, rescue archeological excavations of a Thracian burial mound were conducted four kilometers to the north-west from the town of Primorsko in the locality “Silihlyar”. Foundations of a rectangular feature were discovered in the eastern part of the mound. Its walls followed the cardinal directions and were preserved up to 0.55 m in height. During the excavations of this feature, 40 gold appliqués of a horse harness were found under the walls and the floor. They were spread over an area of cca. 2 m². One of them was found in a mortar layer of the floor, while another seven were between the stones of the northern and eastern walls. The central element of the set represents a decorated shield to which an embossed eagle’s head was attached. The clay lamp buried together with the gold appliqués suggests a deposition date of the set in a relatively narrow chronological range – 333-250 BC.The Treasure of Primorsko is the first fully preserved set of gold decorations for horse harness found to the south of the Balkan Mountains. Further interdisciplinary research is forthcoming.
