Explosion Museum of Naval Firepower


Explosion Museum of Naval Firepower is an award-winning museum of naval warfare set in the 18th century buildings at the Royal Navy's former armaments depot of Priddy's Hard, in Gosport, Hampshire.

Step back in time and wander through the original buildings used to store armaments and weaponry for over 200 years. Immerse yourself in historic displays that tell the story of those who worked at Priddy’s Hard and the weapons they created.

See small arms, cannons and guns as well as the ammunition that was used inside them. Marvel at missiles, torpedoes and mines galore and understand the moral and human stories behind them all.


Alongside developments in munition technology, Explosion Museum tells a human story of the designers, makers, and seamen who worked on armaments over the centuries.

Listen to first-hand accounts of munition workers who dealt with dangerous materials and the dramatic retelling of warfare in the field.

The Explosion Museum in Gosport is the perfect place for an adventure with family and friends. Discover a range of munitions and artillery from cannons to missiles and learn about the workers that created them.
