Original: The river is formed by the confluence, near Colditz, of the Zwickauer Mulde (running through Zwickau) and the Freiberger Mulde (with Freiberg on its banks), both rising from the Ore Mountains.
Simplified: The Mulde is a river in Central Germany. It is formed when the Zwickauer Mulde and the Freiberger Mulde coming from the Erzgebirge meet near Colditz.
