Karlsruhe Castle was built by Margrave Karl Wilhelm von Baden-Durlach shortly after the city was founded in 1715. The landmark of the fan-shaped city in the middle of the Hardtwald served as the seat of the margraves and grand dukes of Baden for almost 200 years before the last reigning grand duke, Friedrich II, fled from the revolutionary Baden troops in November 1918. Today, the former residence houses the Baden State Museum, which attracts numerous visitors, just like the adjacent palace garden. The name “Fächerstadt” (fan city) goes back to the castle. From the castle tower emanate 32 axes, which are cut by a circle stroke and together look like a fan.
