Haus Langen is a former manor. The oldest document about the manor dates back to 1150. In 1276, the manor was completely destroyed by the Bishop of Münster and not rebuilt. The manor was originally surrounded by a large ring wall with three moats, one of which still runs completely around the island of the former castle and the others are still there in fragments.
During the Thirty Years' War, farmers from the surrounding area sought shelter in this ring wall. The building that still exists today is probably a building from the outer bailey of a manor house that was located here, but it was demolished at the beginning of the 19th century. The oldest parts of the preserved building date from the 17th century. The former manor also included a water mill that is powered by the water of the Bever. The mill was first mentioned in 1276 and was initially used as an oil mill, later only grain was ground. The mill was in operation until 1960.
Haus Langen and the still very well preserved water mill are a popular destination for hikers and cyclists and are very idyllically located.
