Biniac has two circular burial navetas that were used around 1400 B.C. and are from an earlier period than the long rectangular constructions like the Es Tudons and Rafal Rubí navetas. The east naveta was built on bedrock and has only one oval-shaped chamber, accessed via a perforated stone slab. Several slabs that had fallen over were found inside. The west naveta is also oval-shaped and the wall on the south side has dry stone cladding, clearly added at a later date.
References: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.
