The type site, in the Balkans near Kiev, of a Neolithic-Copper Age culture which formed in the Western Ukraine and east Romania (Cucuteni culture) in the 4th millennium BC. It is best known for its villages of up to 100 timber longhouses, and for fine polychrome vessels painted with curvilinear and geometric designs. They also had copper and gold objects. Tripolye people practiced shifting agriculture, frequently moving their settlements. The Tripolye culture came to an end with the expansion westwards of steppe cultures of kurgan or single-grave type. The Cucuteni-Tripolye culture was a Neolithic European culture that arose in Ukraine between the Seret and Bug rivers, with an extension to the Dnieper River, about 3000 BC.
