As many other cities in the Czech republic Cesky Krumlov (German name: Krummau) was founded in the 13th century in a strategically convenient position, at a ford in the Vltava river. Initially a castle was built, after which colonists started to settle the area. Following the discovery of silver deposits in the region Cesky Krumlov prospered. After World War II the German speaking population was expelled. Nowadays Cesky Krumlov is a tourist magnet, due to its largely intact historic core and its impressive castle. Cesky Krumlov has been listed as a UNESCO world heritage site since 1992.
