The Arkaim is an ancient city located in the southern Ural Mountains of Russia. It is believed to have been built around the 17th century BC, making it one of the oldest cities in the world. It is also known as the "Russian Stonehen
Arkaim is a fortified archaeological site, dated to c. 2150-1650 BC, belonging to the Sintashta culture, situated in the steppe of the Southern Urals, 8.2 km (5.10 mi) north-northwest of the village of Amursky and 2.3 km (1.43 mi) east-southeast of the village of Alexandrovsky in the Chelyabinsk Oblast of Russia, just north of the border with Kazakhstan. It was discovered in 1987 by a team of archaeologists which later came under the leadership of Gennady Zdanovich. The realization of its importance unprecedentedly forestalled the planned flooding of the area for a reservoir. The construction of Arkaim is attributed to the early Proto-Indo-Iranian-speakers of the Sintashta culture, which some scholars believe represents the proto-Indo-Iranians before their split into different groups and migration to Central Asia and from there to the Iranian plateau, Indian subcontinent and other parts of Eurasia.
