Krzemionki, the newest UNESCO site in Poland
Located in the mountain region of Świętokrzyskie, Krzemionki is an ensemble of four mining sites, dating from the Neolithic to the Bronze Age (about 3900 to 1600 BCE), dedicated to the extraction and processing of striped flint, which was mainly used for ax-making.
With its underground mining structures, flint workshops and some 4,000 shafts and pits, the site features one of the most comprehensive prehistoric underground flint extraction and processing systems identified to date. The site provides information about life and work in prehistoric settlements and bears witness to an extinct cultural tradition. The mining complex is an exceptional testimony of the importance of the prehistoric period and of flint mining for tool production in human history.
