The Healeyfield Parish encompasses the Castleside village area, which is situated two miles south west of Consett and one mile south of the river Derwent, straddling the A68. Because of its location on this main road, it is a popular resting place for tourists heading to and from Scotland. The parish sits on the Coalfield Upland Fringe and the Coalfield Valley. Castleside is situated on the western section of the latter. The Parish also includes Rowley, parts of Knitsley and several outlying farms.
