Uelzen is a town in northeast Lower Saxony, Germany, and capital of the county of Uelzen. It is part of the Hamburg Metropolitan Region, a Hanseatic town and an independent municipality.
Uelzen is characterised by timber-framed architecture and also has some striking examples of North German brick Gothic. The county town earned pan-regional fame when Friedensreich Hundertwasser was selected to redesign the station: the final work of the celebrated Viennese artist and architect was ceremonially opened in 2000 as the Hundertwasser Station, Uelzen, and has since been a popular tourist magnet.
The Polabian name for Uelzen is Wilcaus, possibly derived from wilca or wilsa 'alder'.
