HMS Caroline is a rare survivor of the First World War at sea: a C-class light cruiser that served at the Battle of Jutland and later became a long-term fixture in Belfast. Restored as a museum ship, it adds naval history to the Titanic Quarter's shipbuilding story.
The visit is strongest because you move through an actual warship rather than reading panels in a neutral gallery. Cabins, decks, engine spaces, and interpretation show both the scale of industrial naval power and the cramped daily life of the people who served aboard.
