Portus Adurni

Portus Adurni was a Roman fort in the Roman province of Britannia situated at the north end of Portsmouth Harbour. It was part of the Saxon Shore, and is the best-preserved Roman fort north of the Alps. Around an eighth of the fort has been excavated.

It was later converted into a medieval castle known as Portchester Castle.
