Highlights: The Karlsruhe Palace, a landmark building, is divided into two parts: the palace garden and the Baden State Museum. It was built by the founder of the city, Karl Wilhelm, the frontier count, based on the Versailles Palace. The palace is located in the center of the city, and the surrounding roads lead to the palace in a fan-shaped fashion. The exterior style is a transition from baroque to neoclassical, once destroyed and then rebuilt, with the dual function of official residence and retreat.
