Unfortunately, we have had to close the ramparts at Fort Nelson, due to the poor weather conditions, the Parade Ground will also be closed this week as we deinstall the Standing with Giants display. The museum remains open, Tuesday to Sunday during term time. The safety of our visitors is our main priority. We apologise for any inconvenience caused.
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.
Fort Nelson is free to enter.
