Isca Augusta was a Roman fort and urban centre, whose remains are located nearby or in Caerleon, in South Wales. This is where the II Augustus legion camped, which took part in the invasion of Claudius in 43 CE. It was one of three permanent Roman camps in Britain that survived until the late Empire.
The camp was established in 74/75 CE during the campaign of Sextus Julius Frontinus, who lead the campaign in western Britain. The Roman presence in these areas remained until the beginning of the 4th century CE.
On the site, there are remains of the amphitheatre, thermal baths, barracks and walls of the fort (3.7 m high). In Caerleon is the National Roman Legion Museum, which exhibits artifacts discovered in the area of Isca Augusta (coins, weapons, etc.).
