Liberec (Czech pronunciation: [ˈlɪbɛrɛts] ; German: Reichenberg) is a city in the Czech Republic. It has about 108,000 inhabitants, making it the fifth largest city in the country. It lies on the Lusatian Neisse River, in a basin surrounded by mountains. The city centre is well preserved and is protected as an urban monument zone. Liberec was once home to a thriving textile industry and hence nicknamed the "Manchester of Bohemia". A symbol of the city and the main landmark of the panorama of Liberec is the Ještěd Tower. Since the end of the 19th century, the city has been a conurbation with the suburb of Vratislavice nad Nisou and the neighbouring city of Jablonec nad Nisou.
