Radunia
(重定向自Radaune)

The Radunia (German:'Radaune') is a small river in Kashubia (Pomerelia), which issues from a lake and falls into the Motława (Mottlau) near Gdańsk (Danzig).
A part of its water is conveyed into the city via the 13.5 km long Radunia Channel (Kanał Raduni (pl) / Radaunekanal (de)) or New Radaune, a canal built in the 14th century by Teutonic Knights, to provide water and power to operate the Great Mill (Große Mühle).
