Karlsruhe Palace, which served as a seat of government and residence of the Margraves for nearly 200 years, was built in 1715 and finished in 1718. The palace was given its present decorative appearance in the second half of the 18th century after conversion work and extensions, which can be traced back to the plans of Balthasar Neumann, Albrecht Friedrich von Kesslau, Wilhelm and Jeremias Müller. It was Müller who connected the tower, which originally stood alone, to the central section of the building and crowned it with its characteristic dome.
The castle is now the home to the Baden State Museum and is one of most active and visited cultural history museums in Germany.
