Mannheim Palace is a large Baroque palace in Mannheim, Baden-Württemberg, Germany. It was originally the main residence of the Prince-electors of the Electorate of the Palatinate of the House of Wittelsbach. Part of the palace is used by the University of Mannheim. The State of Baden-Württemberg offers tours of parts of the reconstructed and restored Baroque palace, which features tapestries, furniture, paintings, porcelain and silverware.OriginsThe city of Mannheim, founded in 1606, was fortified and at the present site of the castle there was a fortress called Friedrichsburg, sometimes serving as alternative residence for the Elector, one of the most important territorial princes of the Holy Roman Empire.The actual palace dates from the 18th century. When Elector Karl III Philip had confessional controversies with the inhabitants of his capital Heidelberg, he decided to make Mannheim the Palatinate's new capital in 1720. Karl Philip decided to construct a new palace as his residence on the site of the old Friedrichsburg. It was part of a general trend among the German princes to create grand new residences in that era.Construction was commenced solemnly on June 2, 1720. The building process was intended to cost about 300,000 Gulden, financed by an extraordinary “palace tax”, but in the end, the palace cost about 2 million Gulden and severely worsened the Palatinate's financial situation. The first administrative institutions began using the palace in 1725, but Karl Philip was able to transfer his court to the new residence only in 1731. Construction was not completed until 1760.
