An archaeological watching brief and evaluation was undertaken on land surrounding King's Mill Hospital, Sutton Road, Mansfield, Nottinghamshire. The archaeological work was undertaken in two areas; the East Field, to the east of the hospital; the North Field, to the north. Both fields were previously laid to grass or set aside. Previous archaeological desk-based assessment of the King's Mill Hospital site and the east field had shown that no archaeological remains were known within the area, other than a possible crop mark in the North Field. The lack of any known archaeological sites within the area of the East Field meant that a watching brief was undertaken in the field during the topsoil strip. No features of archaeological significance were recorded in the field. Five sherds of 18th century pottery were recovered from the field, as well as a number of sherds of later date. These are presumed to have originated from manuring scatters. Previous archaeological evaluation by geophysical survey was undertaken within the North Field, which demonstrated a number of anomalies of possible archaeological origin, including a previous known field boundary line. Evaluation by trial trench was undertaken over the area of the possible archaeological anomalies, which demonstrated that most were of geological origin. Watching briefs undertaken in the field during the topsoil strip revealed no finds or features of archaeological significance, other than the line of former field boundaries, land drains, a possible 'well' and the remains of former vegetation/woodland cover. A few sherds of modern pottery were noted within the field, but very few in comparison to the East Field.
