Erected in 1154 as a notable example of the Arab-Norman architecture which flourished in Sicily under Norman rule on the island, the Church of San Cataldo is annexed to that of Santa Maria dell'Ammiraglio. In the 19th century it was restored and brought back to a form more similar to the original medieval edifice.
The church has a rectangular plan with blind arches, partially occupied by windows. The ceiling has three characteristics red, bulge domes (cubole) and Arab-style merlons. The church provides a typical example of the Arab-Norman architecture, which is unique to Sicily. The plan of the church shows the predilection of the Normans for simple and severe forms, derived from their military formation. Moreover, the building shows how international the language of Norman architecture was at the time, as the vocabulary which marks parts of the church, like the bell tower, can be tracked down in coeval buildings like the cathedral of Laon and the Abbaye aux Dames in Caen, both in Northern France, or the cathedral of Durham in England. At the same time, the church shows features shared by Islamic and Byzantine architecture, such as the preference for cubic forms, the blind arches which articulate the external walls of the church and the typical spherical red domes on the roof.
The interior has a nave with two aisles. The naked walls are faced by spolia columns with Byzantine style arcades. The pavement is the original one and has a splendid mosaic decoration. Also original is the main altar.
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.
