Liberec (Czech: [ˈlɪbɛrɛts] (listen); German: Reichenberg [ˈʁaɪçn̩bɛʁk]) is a city in the Czech Republic. It has about 104,000 inhabitants and it is the fifth-largest city in the country. It lies on the Lusatian Neisse and is surrounded by the Jizera Mountains and Ještěd–Kozákov Ridge. The town centre is well preserved and is protected by law as an urban monument zone.
Liberec was once home to a thriving textile industry and hence nicknamed the "Manchester of Bohemia". For many Czechs, Liberec is mostly associated with the city's dominant 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. Therefore, the total area with suburbs encompasses 150,000 inhabitants.
