Archaeologists managed to uncover prehistoric structures at the site of recently discovered circular enclosures, believed to be 7000-year-old Neolithic rondel, located in Nowe Objezierze, West Poland.
A series of concentric cropmarks, indicating the possible presence of a rondel-like structure, has been sighted at Żelichów, North-West Poland. This find is extremely rare as only a handful of such Neolithic structures are known from Poland.
