The Abbey of the Santo Spirito (Holy Spirit), built by the Norman Count Ruggero and his wife Queen Adelasia in 1092–1098, was consecrated in 1153. It has been greatly altered in subsequent centuries. The original outlines are still identifiable to the rear, where its characteristic massive jutting apses can be seen. These are separated by flat pilasters and connected by a series of small arches. The left-hand entrance has an ogival portal from the 13th century. The lunette once contained a figure of Christ Blessing, which was eventually moved inside the Abbey. Notable are the rectangular nave and wooden-beamed ceiling. The walls and the apses have frescoes attributed to the 14th century. The vault of the apse shows a 17th-century figure of Christ Pantocrator.
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.
