National Maritime Museum of Ireland, Maritime heritage museum in Dun Laoghaire, Ireland.
The National Maritime Museum occupies a former church building in Dun Laoghaire and displays ship models, navigation instruments, and maritime objects across several galleries. The collection includes specialized exhibits such as lighthouse optics, ship equipment, and memorabilia from seafaring history.
The building began in 1837 as a church for seafarers and transformed into a museum in 1974. This change came about through an agreement between the Church of Ireland and the Maritime Institute.
The displays show how Ireland has been tied to the sea across time through its people and trades. Visitors encounter ship equipment and papers that bring this maritime connection to life.
The museum is a five-minute walk from Dun Laoghaire train station, making it easy to reach. Opening hours vary by season, so it is wise to check current times before visiting.
The Baily Optic on show was in service at the Baily Lighthouse on Howth Head from 1902 until 1972, when modernisation of the lighthouse removed it. The same gallery holds inventions by John Richardson Wigham. Elsewhere, a clockwork model of the SS Great Eastern sits with items belonging to its captain, Robert Halpin.
