History
Construction of Dún Laoghaire Harbour
Over a period of approximately twenty five years, up to one thousand workers each year laboured in extremely difficult and dangerous conditions to build the magnificent Harbour we enjoy today. This booklet from the accompanying exhibition tells some of their stories.

RMS Leinster
The biggest sea tragedy in Irish history was commemorated in January 1996 when the then Minister of State at the Department of the Marine, Eamon Gilmore TD, unveiled a special memorial in Dún Laoghaire Harbour. The memorial was to the 501 people who lost their lives in 1918, when the RMS Leinster was torpedoed just outside Dún Laoghaire Harbour.
On October 10, 1918 the Mailboat, "The RMS Leinster" sailed out of Dún Laoghaire with 685 people on board. 22 were post office workers sorting the mail; 70 were crew and the vast majority of the passengers were soldiers returning to the battlefields of World War I.
