HMS Belfast, London

HMS Belfast is one of Europe's largest preserved warships. She was launched in 1938 to serve in both World War Two and the Korean War. She is the last surviving example of the great warships built for the Royal Navy. In her day she was one of the most powerful vessels of her type with complex machinery and equipment. During World War Two, she was home to almost a thousand men who had to live in cramped conditions. She retired from service and from protecting the Empire's trade routes in 1965 and has now been converted to a floating naval museum with seven decks for visitors to discover. Children under 16 are allowed in for free.
