Fort Nelson Portsmouth

none

With over 19 acres of tunnels, ramparts and artillery to explore, Fort Nelson is a space where imaginations can run wild.

Overlooking Portsmouth Harbour, this restored Victorian fortress is packed with artillery from across the world. Highlights include a 15th-century Turkish bombard cannon, a gigantic 200-tonne railway howitzer, and the infamous ‘Big Babylon’ Iraqi supergun.

There’s plenty for all ages to enjoy, including free family activities, an onsite café and regularly changing exhibitions.
