Burg Castle, located in Burg an der Wupper (Solingen), is the largest reconstructed castle in North Rhine-Westphalia, Germany and a popular tourist attraction. Its early history is closely connected to the rise of the Duchy of Berg.

The Wupper is a right tributary of the Rhine in the state of North Rhine-Westphalia, Germany. Rising near Marienheide in western Sauerland it runs through the mountainous region of the Bergisches Land in Berg County and enters the Rhine at Leverkusen, south of Düsseldorf. Its upper course is called the Wipper. Both names are related to "weave", and refer to the twisting course.
