After the breakfast, the group will visit the 5th center of civilization Margush/ Gonurdepe. Located north-east site 90 km from Mary city. A remarkable Bronze Age civilization existed here, known variously as Margush, meaning ‘lowland’, or by the Greek name of Margiana. It has been gradually uncovered since the early 1970s by belated Professor Viktor Sarianidi – the leader of Margiana Archaeological Expedition. The Bronze Age sites are to be found at or beyond the northern edge of the present-day oasis, in land which is now desert. Climatic change and progressive desertification caused the abandonment of the area, with the result that the ruins of the Bronze Age settlements are well preserved beneath the desert soils. The Margiana sites seem to have had close ties with those at Bactria, in present-day northern Afghanistan. Sarianidi argues that the Bactria- Margiana complex was a major centre of ancient civilisation, and has speculated that Margiana may even have been a birthplace of Zoroastrianism.
