As a matter of fact it wasn't uranium mine only. First it was a silver mine (XIVth century), then iron mine (from XVIth century), uranium and fluorite mine. The position of the mine is incorrect! The mark shows uranium mine in Kowary! :oops: Now you can explore 7 adits of the mine: over 2 km long.Pictures from Kletno: http://tegroup.org.pl/exploration/galeria/kletno_galeria.htm
