Semiyarka

Semiyarka is a Late Bronze Age settlement in Abai Oblast in north-eastern Kazakhstan, which was occupied from around 1600 BCE. It is connected to the Cherkaskul culture and Alekseevka-Sargary culture, a subdivision of the Andronovo culture. The site includes monumental architecture, and evidence of pottery as well as tin-bronze production. The copper and tin ores used for the production of the Semiyarka artifacts probably originated from the Altai Mountains in East Kazakhstan.
Semiyarka may have been a "Bronze Age metropolis", and is one of the rare known sites of tin bronze production in the Eurasian steppe.
