HMS Belfast is a magnet for kids of all ages. This large, light cruiser – launched in 1938 – served in WWII, helping to sink the German battleship Scharnhorst, shelling the Normandy coast on D-Day and later participating in the Korean War. Its 6in guns could bombard a target 14 land miles distant. Displays offer a great insight into what life on board was like, in peace times and during military engagements.
Excellent audio guides (included in your admission fee) feature anecdotes from former crew members. There's a cafe on-board, and a deli and bar in the visitor centre for landlubbers.
