Karlsruhe Palace was erected in 1715 by Margrave Charles III William of Baden-Durlach, after a dispute with the citizens of his previous capital, Durlach. The city of Karlsruhe has since grown around it. The first building was constructed by Jakob Friedrich von Batzendorf. The city was planned with the tower of the palace at the centre and 32 streets radiating out from it like spokes on a wheel, or ribs on a folding fan.
Originally partially made of wood, the palace had to be rebuilt in 1746, using stone. Charles Frederick, Margrave of Baden-Durlach at the time, and who eventually became Charles Frederick, Grand Duke of Baden then had the palace altered by Balthasar Neumann and Friedrich von Kesslau until 1770, adding larger windows and doors, pavilions and wings. In 1785, Wilhelm Jeremias Müller shortened the tower, adding a cupola.
During the Revolutions of 1848, Leopold, Grand Duke of Baden was expelled in 1849 for some time. In 1918, the last monarch Frederick II, Grand Duke of Baden had to move out. The former residence of the Rulers of Baden is since used as Badisches Landesmuseum.
Much of the city centre, including the palace, was reduced to rubble by Allied bombing during World War II but was quickly rebuilt after the war.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
