To the NNW of Adderstone, lying in an elevated position on a slight hillock in a field known as the Roundabouts, a possible bivallate hillfort surviving only as a cropmark. Two concentric infilled ditches are visible on aerial photographs forming a circle approximately 82m in diameter. The feature was traced by an EH investigator in 1968 who recorded a slight ground swelling in the area of the cropmark. It was recorded as an earthwork on Greenwood's map of Northumberland in 1828 and was probably extant at that time. No internal features are visible and the site is unexcavated and undated.
