Dun Laoghaire is a town on the
Irish Sea between
Dublin and
Bray in
County Dublin. Its name derives from King Laoghaire, an ancient High King of Ireland before the arrival of the Vikings. The English name was Dunlary or Dunleary. It was renamed Kingstown to honor
George IV of England on his visit in 1821 and retained that name until 1921 when it was renamed again.
