Langendorf Castle was first mentioned in 1240. The oldest part of the main building dates back to the 15th century and was expanded around 1498 to include the courtrooms. The castle has been in family ownership since 1880 and was passed on to the then-20-year-old heir Manfred Vetter in 1957 - with the aim of restoring and revitalizing the heavily damaged castle. “Concert in the Barn” - from 1994 to 2010, more than 120 concerts featuring young musicians took place in the barn of the castle. The international historical fire helmet collection with approximately 300 helmets was incorporated into the foundation in 2010. The open-air stage, used only ten times, was donated to the Euskirchen district at the end of 2010 for events by schools, clubs, and others. The castle (cellar ground floor and outside) is available for group tours by arrangement.
