When magnificent Djerdap dam on the river Danube was being constructed during 1960s, prehistoric settlement of Lepenski Vir was accidently uncovered some 20 km west from town of Donji Milanovac. Group of archeologists led by Professor Dragoslav Srejovic was summoned up and the whole site was relocated, enabling both archeological research and dam construction.
Excavations uncovered prehistoric urbanized settlement with central square used for public and religious gatherings. Primitive houses stood on trapezoid bases that can be seen on the archeological site, now opened for public as a part of Lepenski Vir museum complex. Fish like, humanoid figurines were also uncovered with symbols and signs still undeciphered, alongside various object and tools made of stone and bone. Lepenski Vir civilization reached its peak in-between 6 500 BC and 5 500 BC and as such, it is not only locally, but globally important Middle Stone Age or Mesolithic discovery.
