Ireland’s National Maritime Museum is housed in Dun Laoghaire’s 180-year-old Mariners Church, directly opposite the new DLR Lexicon library and easily accessible by DART suburban train and several bus services.

The museum’s greatest artefact is probably the building itself as it is one of a few custom built places of worship for seafarers remaining intact in the world today.

Experienced guides will bring you on a voyage of discovery, enthralling you with stories of discovery, heroism, war and disasters at sea. You will learn about maritime history, exploration, navigation, radio, deep-sea cable technology, nature, wildlife and view art inspired by the sea.

It will give you a first-hand impression of the Museum as it used to be, a church of worship, a Mariners Church
