the largest flint mines of the Neolithic period in Europe. Located in southern Poland in the valley of the Kamienna River, a left tributary of the Vistula River (Opatów District, Kielce Województwo), they were discovered in 1919. More than 700 mines up to 11 m deep have been unearthed. Axe parts and ancient mining tools have been found. A large Aeneolithic settlement with numerous workshops has been excavated in Cmielów, 9 km from Krzemionki Opatowskie. Axes were made in these workshops from the banded flint mined in Krzemionki Opatowskie, which then made their way into northern Europe. Krzemionki Opatowskie and the Aeneolithic settlement in Cmielów are part of the southern group of remains of the Funnel-Beaker culture.
