Best of Maritime Ireland | The National Maritime Museum in Dun Laoghaire

Within the unique setting of a converted mariners church lies the volunteer-run National Maritime Museum in Dun Laoghaire. The wonderfully presented museum hosts an impressive range of maritime history artefacts and exhibits and is really worth a visit for anyone with a love of Ireland’s coast.

The building was originally a Mariners Church built in 1830s and used as a place of worship for officers, sailors and seafarers who came into the busy port of Kingstown. Over time the congregation dwindled and the church shut down. It was handed over to the Maritime Institute of Ireland as a fitting location for a museum, keeping the maritime spirit of the building alive.


In 1978 the National Maritime Museum of Ireland was opened by President Patrick Hillery and it has been growing ever since.




The museum is filled with a huge collection of artefacts, models, paintings and photographs that cover all aspects of Irish maritime heritage. It tells the stories of maritime greats, legendary captains and all the tales of struggle, success and loss that go along with the sea.

Fascinating Exhibits Bailey Optic from the Howth lighthouse

There are thousands of objects throughout the museum one of the most eye catching is the Baily Optic, a functioning lighthouse optic from the Baily Lighthouse in Howth. The Optic stands impressively on the former altar,  rotating and shining it’s light over the museum. It was donated by Irish Lights and was installed within the Bailey Lighthouse from 1902 -1972. The light is dimmed some what now but originally the light was equivalent to 2,000,000 candles.
