Priest's Doorway. Lower section of W tower probably Anglo-Saxon. Otherwise 12thc. and later. On W front, small late 12thc. pointed arch set into large semicircular arch that may be either Anglo-Saxon or early 12thc. Some Anglo-Saxon sculpture is set in the inner nave walls of the church.

Diddlebury was given by Roger Mortimer, holder of the county of Shropshire, to the Abbey of Shrewsbury by 1086. In 1255 the collegiate church of St Mary, Bridgnorth, was claiming an annual rent from the parish.

The large human head above the apex of the small W doorway may be Anglo-Saxon.
