At the edge of Salter's Nick crags are the remains of a Romano-British settlement. It consists of a curving rampart, built of earth and stone, which encloses an area about 70m north-east to south-west by 48m. The rampart stands up to 1m high and is 6m to 8m wide. Inside the enclosure the remains of at least three stone hut circles are visible, each about 9m in diameter. Other earthworks nearby are believed to be part of an earlier settlement of Iron Age date, but the later settlement has masked any surviving internal features. This is a Scheduled Monument protected by law.
