Hirschburg Manor

The Hirschburg is a historicist country villa with a castle-like character in Königswinter, a city in the Rhein-Sieg district of North Rhine-Westphalia, built in 1883/84. It is located below the ruin of the same name, Hirschburg, on the western slope of the Hirschberg (256 m above sea level), east and above the Nachtigallental. The Hirschburg is a protected architectural monument.

The builder of the estate was Jacob Anton Biesenbach, brother-in-law of Baron von Sarter, for whom Biesenbach had previously built Schloss Drachenburg, located on the other side of the Nachtigallental. The Hirschburg adopted its Neo-Gothic stylistic elements from this building. The architects Gerhard Franz Langenberg and Wilhelm Hoffmann contributed to the design. After Biesenbach's death, the Hirschburg came into the possession of the Cologne family von Malinckrodt in 1899, and in 1910 to the Cologne wagon manufacturer Paul Charlier.

In 1933, the Hirschburg was acquired by Mannesmannröhren-Werke. Initially, its use as a mother and child home was planned, but from 1943 it was first used as an administrative building for the company. From 1950, it served as a recreation home for Mannesmann employees. In 1972, a new guesthouse was built below the Hirschburg. In 1992, the Roermond earthquake caused damage that necessitated renovation work on the building. Mannesmann then decided to set up a seminar and conference center in the Hirschburg. The Hirschburg was entered into the monument list of the city of Königswinter on September 29, 1995.

After the company was taken over by Vodafone, the Hirschburg was renovated in 2001/2002 under the direction of Michael Deisenroth and has served the new owner, including the surrounding buildings, as a conference venue since 2003.
