What you need to know
We've made some changes to help keep you safe, and things might be a little different when you visit. Here's everything you need to know.
Visit the Castle Keep
Explore the keep of one of the most impressive and best preserved of the 'Saxon Shore' forts.
Uncover the story of Portchester's Prisoners
From 1665 Portchester served as a prisoner-of-war camp – a role that reached its height during the French Revolutionary and Napoleonic wars of 1793–1815, when it housed up to 8,000 prisoners, of many nationalities and backgrounds, at any one time. Today, enjoy our exhibition telling the story of these prisoners, and explore their life at the castle.
