Kandava settlement was first mentioned in 1230 in a peace treaty between the residents of Riga and the residents of the Abava valley in Courland. A military castle was built around 1257, but it was gradually dismantled over the years and now only its foundations can be seen in a town park. The oldest remaining structure is a guard tower built in 1334 and later used for gunpowder storage.
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.
