The Royal Navy Submarine Museum
“Really interesting museum, have to admit didn't spend too long in the main museum, most of the visit was concentrated on HMS Holland, amazed a submarine this old has survived, houses in a brilliant gallery. HMS Alliance, was really great to look around, there aren't many places you can go on board and explore a 1940's submarine, bit cramped, but well worth it and the submariner on board was really helpful with questions. If you are visiting the dockyard, well worth popping over and having a look around.”
