The settlement and necropolis of Grakliani Hill are located in Central Transcaucasia, Georgia. Excavations of the settlement on the eastern slope and the necropolis on the south-western part of the hill demonstrated that the site had been occupied between the Chalcolithic and the Late Hellenistic periods. The most interesting remains of buildings belong to 2nd and 1st millennium BC. Several sanctuaries of this period were excavated. A monumental altar was discovered in the eastern part of the settlement. The altar was located in the north-western corner of a building. On its eastern side there was an ash pit with a platform along the northern wall. The platform was used for placing offerings, including a South Mesopotamian seal. An architectural complex of the following period (450-350 B.C) was discovered in the western part of the lower terrace. It consisted of three main rooms and three store-rooms. Burials of various periods were discovered in the western part of the hill’s southern slope. The earliest one is a pit-burial dating to the Early Bronze Age, the latest one belongs to the 2nd century BC. After analyses of the finds several directions of cultural and commercial links were identified: Colchis, Persia, Phoenicia, Mesopotamia, Egypt, Asia Minor.
