The Gannarve grave is outlined by large standing stones, forming the shape of a ship. It has been built at the end of the Bronze Age, about 1100 – 500 B.C. The grave is 29 metres long and 5 metres wide. It is only one of about 350 boat-shaped graves on the island. In most cases, only one burial has been uncovered in each grave. When these people were buried, it was a custom to cremate the dead on a pyre. After cremation, the bones were crushed and washed before they were placed in an urn.
There were once two boat-shaped graves here at Gannarve. One of them fell victim to the plough long ago. The existing grave was almost destroyed in the same way. Only the stem stones remained when archaeologists started excavating the monument in 1959. The excavation uncovered soil marks of all the removed stones beneath the peat. Consequently, the reconstruction of the entire grave was not too difficult.
There were plenty of large stones lying right next to the grave, and it is quite possible that several of the stones used once actually belonged to the original grave.
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.
