Your visit to the Submarine Museum

The Museum will be closed for just one day on Monday 24 June due to vital conservation work.

 "Easily the best attraction in the area...we’ll be back!” 

Dive into history....come onboard, meet the crew and discover what life was like living under the sea.

Meet the crew...

CHAT WITH our submariner guides as they take you through our submarines and find out what it was like to face danger in battle; to share jokes in the cramped living conditions and how the torpedo section doubled up as a food store and cinema.

“Almost made you feel part of the crew”

Dive deeper...

STEP ONBOARD Holland 1, the Royal Navy’s first submarine built in 1901 crewed by only eight men and three mice!  Peer into the X24, the only remaining midget submarine to have served during WW2. Keep watch for enemy ships through the working periscopes of the Falklands Conflict submarine HMS Conqueror.

“The best museum I’ve ever been to”

Dive into fun and games...

FEEL THE FORCE and try your hand at keeping a submarine buoyant, understand sonar pings and fight the enemy in the interactive science gallery.  Meet also our submariner Sammie Sardine and find out just how smelly submariners were, the ghastly food they ate and the poo fountains!

“My grandson loved it”

Dive into a sticky cake...

Relax with a frothy coffee and gorgeous cake in our Coffee Shop with views overlooking Portsmouth Harbour.

Saving history...

HMS Alliance the UK’s only surviving British WW2 era walk through submarine is currently undergoing a major conservation programme so access may be disrupted.
