Narrow Water Castle is a famous 16th-century tower house and bawn near Warrenpoint. In 1212, a keep was built on the site by Hugh de Lacy, first Earl of Ulster, to prevent river-borne attacks on Newry. In the 1560s, the tower house and bawn were built. It is a typical example of the tower houses built throughout Ireland from the 14th until the early 17th century. This kind of building, normally rectangular in plan and three or more storeys high, comprised a series of superimposed chambers, with stairs, closets and latrines skillfully contrived within the walls (which are 1.5 metres or five feet thick in places) or sometimes contained in projecting angle turrets. The original was destroyed in the 1641 Rebellion.
On 27 August 1979, 18 British Army soldiers were killed by a Provisional IRA ambush at Narrow Water Castle (see Narrow Water ambush). It was the greatest single loss of life for the British Army during The Troubles.
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.
