Located at an altitude of 443 metres at the end of the ridge, Château de l'Ortenbourg was built between 1260 and 1265 by Rudolf Habsburg to the site of older castle. It is one of the most beautiful ruins in the Rhine Valley.
In 1291, on the death of Rudolf, Otto IV opposed the election of Albert of Habsburg and supported Adolphe de Nassau. In 1293, Otton joined the siege and had the Ramstein built to take Ortenbourg; and after three weeks of sieges, the Austrians surrendered and the Val de Villé was invaded by Otto.
From the 16th century the castle started to dilapidate as a result of a lack of maintenance, although it is inhabited until the beginning of the 17th century. In 1633 the Swedes set fire to the castle.
Today Ortenbourg is a masterpiece of military architecture with its high shirt surrounding a 32-meter dungeon, is visible from a distance and fits remarkably in the landscape. This dungeon offered 6 levels of defensive fire and its pentagonal design allowed for better deflection of the attackers' projectiles.
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.
