National Maritime Museum of Ireland

The National Maritime Museum of Ireland is housed in the former Mariners' Church in Dún Laoghaire, a historic building overlooking the harbour. The museum tells the story of Ireland's rich maritime heritage through a variety of exhibits. Highlights: The Baily Optic (giant lighthouse lens), ship models, uniforms, and artefacts from the Titanic and Lusitania. Ages: Suitable for all ages, but especially fascinating for kids aged 5+ interested in ships and the sea. Facilities: Toilets, gift shop, and nearby cafes. Limited hands-on exhibits, but the large lens and model ships are engaging. Practical tips: Admission is free (donations welcome). The museum is small, so combine with a walk along Dún Laoghaire pier or a visit to the nearby playground.
