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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
