History
The knight's seat was first documented in 1329 and passed through the hands of several noble families over the centuries. The place name "Leidenhausen" dates back to the 7th to 9th century and roughly means the settlement of an owner named Leido. The building complex took on much of its present form under the barons of Hatzfeld in the 16th and 17th centuries, and later under the barons of Weichs and the counts of Mirbach-Harff in the 18th and 19th centuries. Until 1803 the estate also served as the administrative centre for the entire area between Bergisch Gladbach and Siegburg.
From working estate to city property
After the forests east of the Mauspfad were expropriated and added to the military training ground, Theodor von Mirbach-Harff sold the estate to Ferdinand Mülhens senior, who turned it into a farm supporting the Röttgen stud. Around 1920 and 1930, gaps in the buildings were filled with stables and barns, creating today's enclosed courtyard with its distinctive archway. In 1963 the City of Cologne acquired the property, which was still run as a large farm until 1964.
Today: environmental education and nature
In 1982 the nature museum "Haus des Waldes" was established in the eastern barn wing, whose educational room is used by the forest school of the Schutzgemeinschaft Deutscher Wald. Since 1 July 2018 Gut Leidenhausen has officially been the City of Cologne's environmental education centre and part of its environmental education concept. Between 2018 and 2021 it received annual funding of €220,700. The aim is a broad, free programme of environmental education and nature experiences for children, young people and adults, developed in close cooperation with the initiatives already active on site.
Good to know
- The name refers to an early-medieval estate owner called Leido.
- The striking archway of the enclosed courtyard only emerged through the additions and rebuilding of the early 20th century.
- Its position at the transition between the Wahner Heide and the Königsforst makes the estate a nature-focused starting point.
