Landsberger Hof

Landsberger Hof in Arnsberg, Germany is a town palace erected in 1605 by Elector Ernst of Bavaria, an early 17th-century French-influenced city residence that became a center of local princely administration in the Duchy of Westphalia. From its construction the house played a public role: it passed between private owners with close ties to the electoral court and served repeatedly as the seat or lodging of senior electoral officials and visiting electors, making it a focal point for regional government and justice over several centuries.

Shortly after completion the Elector transferred the house to Gertrud von Plettenberg, who managed princely castles in the area and acted as Ernst’s long-term companion. On Gertrud’s death ownership passed to her daughter Katharina, who left Arnsberg after marrying a nobleman in Spanish service. While Katharina was absent the building was let to the Electorate for an annual rent.

During the long rule of Elector Ferdinand of Bavaria (1612–1650) the Electorate paid Katharina, then a nun in Belgium, a lump sum of 4,000 gulden intended to benefit her convent church in France. In this period the house served as the residence and workplace of the Landdrost, the highest electoral official in the duchy, housing the administration charged with enforcing the Electorate’s authority in Westphalia.

Under Elector Maximilian Heinrich the Electorate bought the property outright. The regional estates later conveyed the house to the Landdrost Daniel Dietrich von Landsberg in recognition of his services, and the complex thereafter became known as the Landsberger Hof. The von Landsberg family retained ownership until 1921, although public bodies made increasing use of the premises from the 18th century onward.

A major rebuilding took place between 1733 and 1741 after a fire, and later, when the local castle was destroyed in 1762, Landsberger Hof became the residence for the Electors of Cologne during their stays in Arnsberg. With the approach of French revolutionary armies the electoral administration fled Bonn, and from 1794 the building served as the seat of the Electorate’s High Court of Appeal. Under Hesse-Darmstadt rule from 1803 it housed central government offices including the treasury chamber and the war commission. After transfer to Prussian control from 1816 it became the office and residence of the first regional government president, von Bernuth.

From 1825 the palace accommodated the Royal Court (Königliches Hofgericht), and later, after a new courthouse was provided, it held institutions such as the Upper Postal Directorate. Nineteenth-century municipal plans to convert the property into a girls’ school failed when the von Landsberg family set an asking price the city would not meet. The city eventually acquired the complex and used it for the volunteer fire brigade and a local history museum. For financial reasons during the Second World War the city sold the property to the District of Arnsberg; it later passed to the Hochsauerlandkreis.

After 1945 the building served a sequence of institutional uses: a school for children of Belgian soldiers stationed in Arnsberg, an information office called Die Brücke, and offices for the regional district police. Following the fire brigade’s departure in 1959 the war-damaged structure was carefully restored, and since 1964 the restored palace has housed the regional-history Sauerland Museum, with a museum café occupying one of the outbuildings.
