About 12km northwest of Kassel you'll find one of Germany's best-preserved and most beautiful rococo palaces, built by Landgrave Wilhelm VIII as a leisure palace between 1747 and 1761. The magnificent Baroque park-like grounds are free to explore, while the sumptuous interior can be visited on a (highly recommended) hourly guided tour. Among the many delightful rooms, visitors love the master kitchen, where the Bratenwendemaschine (roast turning machine) still functions.
To get here from Kassel, take the B7 north to Calden and follow the signs, or from Wilhelmshöhe, take the L3217 north and follow the signs.
