Fürstbischöfliche Schloss, the grand baroque castle was constructed in 1767-1787 as the new residence of the penultimate prince bishop of Münster Maximilian Friedrich von Königsegg-Rothenfels. The architect of the building was Johann Conrad Schlaun. He selected his favourite combination of light sandstone and red brick as the construction and decoration material. However the author of the project did not live to see the end of the construction. After his death in 1773 the construction was finished by Wilhelm Ferdinand Lipper, adherent of classicism, which showed on the interior design.
In 1784 the prince bishop who had ordered the construction died too. His successor preferred to live in Bonn, not in Münster, that’s why he did not need the new residence. The castle found its application after secularization of Münster in 1803, when the largest part of the principality’s lands went to Prussia. The palace was then occupied by the Prussian governor. Since 1815 the palace was the residence of the ober-president of the province of Westphalia.
Since 1954 the castle belongs to the Westphalian Wilhelms-University. Three times a year a popular fair Send is conducted in the square in front of the castle.
