Mannheim Palace is a large Baroque palace, originally the main residence of the Prince-electors of the Electorate of the Palatinate of the House of Wittelsbach. It is now primarily used by the University of Mannheim.
The 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.
Karl Philip died in 1742 and was succeeded by a distant relative, the young Karl Theodor. During his reign, the palace and the city of Mannheim saw their zenith. The glamour of the Elector's court and Mannheim's then famous cultural life lasted until 1778, when Karl Theodor became Elector of Bavaria by inheritance and he moved his court to Munich. Although Mannheim kept the title of “residence”, the palace was used merely as accommodation for several administrative bodies.
Things worsened further during the Napoleonic Wars, when Mannheim was besieged. During Napoleon's reorganization of Germany, the Electorate of the Palatinate was split up and Mannheim became part of the Grand Duchy of Baden, thus losing its capital/residence status. Some glamour returned to Mannheim Palace when Stéphanie de Beauharnais, the consort of Grand Duke Karl of Baden, resided here after 1806. For most of the 19th and early 20th centuries, the palace served no uniform purpose, being used as a representative building and a museum for the city.
In World War II, the palace was heavily bombed and partly destroyed. Many people supported demolishing it after the war to create space for a more modern city architecture. These plans came to nothing and the palace was reconstructed.References:
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
