Dún Laoghaire

The fort is said to have been Lóegaire's sea base for raiding Britain and Gaul. The town as it stands was built after 1816 legislation allowed a great harbour to serve Dublin. It was renamed Kingstown in 1821 when George IV sailed from it, and took its own name back in August 1920.

Dún Laoghaire is generally taken to be the fort of Lóegaire mac Néill. In 1728 it was a small fishing village called Dunleary. The loss of two troopships on the rocks near Blackrock in November 1807, with more than 400 lives, drove the campaign for an "asylum harbour", and when George IV visited the harbour works in 1821 the town was renamed Kingstown in his honour; it took back its old name in August 1920.

Ireland's first railway opened from Westland Row to Kingstown on 17 December 1834, and the town became a Victorian suburb and seaside resort. British troops landed here in April 1916 to march on the Rising. An anchor by the Carlisle Pier comes from the mailboat RMS Leinster, torpedoed off the Kish in 1918 with the loss of more than 500 lives.
