Remains of a medieval chapel, probably established as a manorial chapel by the founder of the motte and bailey castle to which it is associated and formerly a chapel of ease to Glasbury. The structure comprises the foundation of the nave and chancel, now incorporated into a dillapidated drystone enclosure. The structure measures c. 18m from E to W by 6m transversely within footings 0.6m in thickness.
