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.

Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
