Wulp Castle was built during the high Middle Ages. Despite this, the castle is documented only in a few found texts, and much of the castle's history is not known. However, in the chronicle of Muri Abbey, a castle that could perhaps fit Ruine Wulp's description - a castle in proximity to Zurich and Lake Zurich - was mentioned, but this has not been confirmed by other findings and is mere speculation. Also, a person named Eghart of Küsnacht was mentioned in the chronicle and several other documents to be the owner of the castle in the late 11th century. The castle was probably destroyed or abandoned already in the 13th century.
While no cemented and sure truth about the castle can be confirmed, progress has been made, including the finding of Bronze Age remnants after the excavation of the castle site, such as palisades. Other items have been uncovered about the castle's past, such as the altering of the castle in the 13th century, when it is presumed that most or all of the castle was replaced with a single tower and a central building, with only sections of the main wall still existing. After an unknown period of time, the Barons von Regensbergare known to have assumed ownership of Ruine Wulp, and also are known to have made plans to completely renovate the castle, but the plans probably were never realised.
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.
