Karlsruhe Palace (German: Karlsruher Schloss) was erected in 1715 by Margrave Charles III William of Baden-Durlach, after a dispute with the citizens of his previous capital, Durlach. The city of Karlsruhe has since grown around it and was planned with the tower of the palace (Schloss) at the centre and 32 streets radiating out from it like spokes on a wheel, or ribs on a folding fan, so that a nickname for Karlsruhe in German is the "fan city" (Fächerstadt).
