Kong Asgers Høj (King Asgers Mound) is a large passage grave on the island of Møn. It was built in the Late Stone Age (3000 BC - 1500 BC) and has a 10 meters long narrow passage leading into to the grave chamber. The grave chamber is 10 meters long and 2 meters wide and was when in use a common grave. When somebody died the grave was opened, the deceased was buried, and the grave was closed again. Kong Asgers Høj is situated to the Northwest of Sprove on a small hill. The passage grave is open to the public, but it is a good thing to bring some sort of light because the grave chamber is pitch-dark.
Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
