Noviomagus Reginorum was Chichester's Roman heart, very little of which survives above ground. It lay in the land of the Atrebates and is in the early medieval-founded English county of West Sussex. On the English Channel, Chichester Harbour, today eclipsed by Portsmouth Harbour, lies 4+1⁄2 miles (7 kilometres) south.
