Built into the side of a limestone cliff, the St. Govan's Chapel measures 6.1 m × 3.7 m with walls constructed from limestone, and consists of two chambers, one in the front and one in the back. The majority of the chapel was built in the thirteenth century, although parts of it may date back further to the sixth century when Saint Govan, a monk moved into a cave located on the site of the chapel. One legend suggests that Saint Govan is buried underneath the chapel's altar, located at the east end of the building. The entrance to the building is via. a doorway on the north side, low stone benches run along the north and south walls and an empty bell-cote is located at the west end. The slate roof is suspected to be a modern addition compared to the rest of the building.
The building is accessible from the clifftop by climbing down a set of 52 stairs, although tourist organisations propagate the legend that when counted, the number of steps differs between going down and going back up.
The building was listed with Grade I status on August 2, 1996. The chapel is within the Castlemartin Military Training Area and is sometimes inaccessible.
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.
