Dún Laoghaire
suburban seaside town in County Dublin, Ireland
Dún Laoghaire ( dun LEER-ee, Irish: [ˌd̪ˠuːn̪ˠ ˈl̪ˠeːɾʲə, - ˈl̪ˠiːɾʲə]) is a suburban coastal town on the southside of Dublin, Ireland. It is the administrative centre of the county of Dún Laoghaire–Rathdown. The town was built up alongside a small existing settlement following 1816 legislation that allowed the building of a major port to serve Dublin. It was known as Dunleary in the English language, until it was renamed Kingstown in honour of George IV's 1821 visit, and in 1920 was given its present name, which is the original Irish form from which "Dunleary" was anglicised. Over time, the town became a residential location, a seaside resort, the terminus of Ireland's first railway and the administrative centre of the former borough of Dún Laoghaire, and from 1994, of the county of Dún Laoghaire–Rathdown.
Toponymy
The town's name means "fort of Laoghaire". This refers to Lóegaire mac Néill (modern spelling: Laoghaire Mac Néill), a 5th-century High King of Ireland, who chose the site as a sea base from which to carry out raids on Britain and Gaul. Traces of fortifications from that time have been found on the coast, and some of the stone is kept in the Maritime Museum. The name is officially spelt Dún Laoghaire in modern Irish orthography and in general usage. It is sometimes unofficially written as Dún Laoire.

Why this record matters
“Dún Laoghaire” is worth following because a concise public description often conceals a longer documentary argument. Here, Laoghaire, suburban and seaside provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q745989. VIAF identifies the subject as 142558965. The Library of Congress control number is n83301217. Authority coordinates are 53.300, -6.140. 4 of 5 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 1816, 1821, 1920 and 1994.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
