St Mary's Church dates from the twelfth century. At this church the Rev. Legh Richmond is thought to have originated the now globally popular idea of using boards with movable numbers to indicate hymn numbers during church services. The 13th-century tower is of a very unusual style in that it is built on four piers at the entrance to the church. This is one of only four in examples in Britain. The tower contains a ring of 8 bells which the heaviest weighs 10.5cwt in the key of G. The oldest bell was made in 1594.
The current church building has aspects dating from the late 12th century onward, with the majority of the present building resulting from the alterations of the 14th and 15th centuries. The Oglander Chapel on the eastern end of the south aisle is the resting place of members of that family and includes two elaborately carved and painted wooden effigies of knights placed upon two of the tombs. Whilst installed by the family itself, their appearance does not represent the accurate historical dress of the time for the family members in the tombs beneath. In the north aisle there are funerary hatchments of the Oglander family on the walls, and two fonts from the 13th and 15th centuries.
The churchyard contains the Commonwealth war graves of four British Army soldiers of World War I.
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.
