Nicknamed the Swabian Versailles, the Residenzschloss is an extravagant 452-room baroque, rococo and Empire affair. The 90-minute chateau tours (in German) begin half-hourly; there's a English tour at 1.30pm.
The 18th-century feast continues with a spin of the staggeringly ornate, scarlet and gold Karl Eugen Apartment, and three museums showcasing everything from exquisite baroque paintings to fashion accessories and majolica.
