Olkusz [ˈɔlkuʂ] (German: Ilkenau, Yiddish: עלקיש 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.
The city is on the Baba river, with a major road reaching it from Warsaw and Kraków, making it the central city of the vicinity. Tourists who wish to visit the nature and historical sites, start from here. Also, Olkusz is located on the main railroad line, which connects Upper Silesia and Zaglebie with Kielce.
According to the city website, a fable is mentioned that the city was formed by ancient Phoenicians who traveled here and found lead ore. The origin of the name is the Phoenician El-Khuds meaning to chisel.
A first written historical document from the year 1299 refers to the city of Olkusz, located in the Lesser Poland province of the Kingdom of Poland. The city was initially ruled by citizens of German descent, and the inhabitants were mostly wealthy, due to the lead mines. Silver was discovered too. Various wars crossed the path of this city, which was at its lowest at the end of the 17th century (see: The Deluge).
