Kořenov (German: Bad Wurzelsdorf) is a municipality and village in Jablonec nad Nisou District in the Liberec Region of the Czech Republic.
The Jizera River forms here the entire Czech-Polish border and then shortly crosses the territory of Kořenov.
The first settlers came to the remote forested area in northern Bohemia in 1577 when Paul Schürer von Walthaimb established one of the oldest glassworks in the region at Rejdice.
[10] After the 1620 Battle of White Mountain, the lands were seized by Albrecht von Wallenstein, who sold them to the comital Desfours dynasty.
The municipality was established in 1960 by the merger of the former market towns of Polubný and Příchovice with Rejdice and Jizerka.
[12] Part of Kořenov, the former hamlet of Údolí Naděje (Hoffnungstal, Polish: Zieleniec), belonged to Poland between 1945 and 1958.
