Brief SynthesisLocated at the junction of Bronze Age trade routes crossing the Iranian plateau, the remains of the mud brick city of Shahr-i Sokhta bear witness to the emergence of the first complex societies in eastern Iran. Criterion (ii): Shahr-i Sokhta exhibits a transition from village habitation to an urbanized community with significant cultural, social and economic achievements and developments from the late Calcolithic to the early Bronze Age. AuthenticityIn general the surrounding desert landscape and extraordinary scatter of archaeological material present on the surface of the low hill of Shahr-i Sokhta give a strong sense of authenticity, as does the sight of the complex architecture of the various parts so far excavated. Shahr-i Sokhta was registered in the list of national cultural properties of Iran as no. The archaeological excavations and finds have been documented since the 1970s and records, inventory and finds are stored and analysed at the ICHHTO multi-disciplinary Base at Shahr-i Sokhta.
