Surrounded by French-style gardens, this château (1755-70), built by the architect Nicolas de Pigage for the Prince-Elector of the Palatinate, is pure Louis XV in layout. The apartments have retained their original decoration in a very sober Rococo style which is a forerunner to Classicism and are furnished with magnificent pieces dating from the second half of the 18C. The two low wings are home to a museum dedicated to European garden art and a natural history museum.
