Olkusz
Olkusz ( Elkish) is a town in south Poland with 36,607 inhabitants (2014). Situated in the Lesser Poland Voivodeship (since 1999), previously in Katowice Voivodeship (1975–1998), it is the capital of Olkusz County. From 1941 to 1945, the occupying Germans renamed the region to Ilkenau. Olkusz is called 'Silver Town" because of the large amount of silver that was found and mined here.
