From the baroque-meets-neoclassical Schloss, Karlsruhe’s 32 streets radiate like the spokes of a wheel. Karl Wilhelm, margrave of Baden-Durlach, named his epicentral palace Karlsruhe (Karl’s retreat) when founding the city in 1715. Destroyed during WWII, the grand palace was sensitively rebuilt. In warm weather, locals play pétanque on the fountain-strewn Schlossplatz parterre. The palace harbours the Badisches Landesmuseum.

Edging north, the Schlossgarten is a popular student hang-out and a relaxed spot for walks and picnics.
