Nebelivka
Nebelivka, or Nebelovka, in Ukraine, is the site of an ancient mega-settlement dating to 4000 B.C. belonging to the Cucuteni-Trypillian culture. The settlement was for the time huge, covering an area of 260-300 hectares and home to perhaps 15,000 - 17,000 people. The settlement within the boundary ditch includes over 1200 structures. Research from 2012 to 2014 imply "the possibility of state-level societies", contemporary with similar developments in Uruk. Mega-structures "suggest the presence of public buildings for meetings or ceremonies".
