A Neolithic flint mine in Poland has been nominated for inclusion in the UNESCO World Heritage List.
The announcement means that the mine could become internationally famous, public broadcaster Polish Radio’s IAR news agency reported.
The UNESCO list includes sites such as the Great Wall of China and the ancient Egyptian city of Thebes.
The flint mine in Krzemionki Opatowskie, south-central Poland, was nominated alongside 27 other sites considered to be of great cultural value to humanity.
A total of 1,092 locations in 167 countries are listed as world heritage sites. Fifteen of them are in Poland.
Krzemionki Opatowskie is one of the largest known complexes of prehistoric flint mines in Europe.
The mining of flint – once used to make implements such as axes – began there about 4000 BC.
