Discover the story of the Royal Navy under the sea at the Royal Navy Submarine Museum, which is the only submarine dedicated museum in Europe. Telling the story of the Royal Navy’s submarine service, visitors can go onboard the submarines and meet a real submariner to hear his stories about living beneath the waves.

Set on the site on the submarine service’s 20th century base on the Gosport side of Portsmouth Harbour, the museum is home to the Royal Navy’s very first submarine Holland 1 and the only surviving WW2 era submarines remaining in the UK, the mighty HMS Alliance and midget X24.

This family friendly museum has working periscopes, hands on interactive games, the “Horrible Science of Submarines” exhibition and a brand new family play centre Busy Boats Bay.  Complete your visit with a frothy coffee and a sticky cake at the Harbour Stations coffee shop overlooking Portsmouth Harbour.

HMS Alliance is the centrepiece of the Museum and is the official memorial to the courageous men who fought in similar boats for the freedom we enjoy today. The submarine experience is brought to life by a guided tour enhanced by the first hand experiences of retired submariners, many of whom served in this class of boat.
