English Heritage

This fascinating site overlooking Portsmouth harbour has been a Roman fortress, a Norman stronghold and even a prisoner of war camp during the Napleonic Wars. Discover what life was like for the soldiers held here with sound installations, marvel at the well-preserved remains of the Roman fort and climb to the top of the 30-metre (100 ft) keep to take in breathtaking views over the Solent. Make the most of the wide open grounds and castle courtyard, and enjoy a family picnic surrounded by history.
