Hornberg Castle was probably originally built in the late 12th century. The first mention of the castle dates from 1184. In 1259 lords of Hornberg sold the castle to the bishop of Speyer. Since 1612 it has been owned by the 12th generations of Gemmingen barons. Today the castle is a hotel.
Hornberg originally consisted of two separate castles. Between them was a bailey. Around 1510, both castles were enclosed together with the a common wall as an additional attachment of Conz Schott of Schottenstein.
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.
