An Eneolithic and Early Bronze Age site in central Bulgaria which lends its name to a culture of the lower Danube basin and the Black Sea coast of Bulgaria. There were two building phases of the Veselinovo culture (Karanovo III) dated c 4320 BC, a level with Karanovo IV pottery, eight building levels of the Copper Age (Karanovo V-VII) dated c 3630 BC, and nine building levels of the Early Bronze Age. The Bronze Age levels have radiocarbon dates of c 2500-2200 BC and the pottery has affinities with the Early Bronze Age of Troy. Ezero had a very rich bone, antler, and stone industry and provides the most detailed chronology for southeastern Europe for the time period.
