The remains of chancel arch, on the south side of building with restored inscription on 15 voussoirs which commemorates a certain Magnus of Danish royal stock who chose to become an anchorite at this church. Set into the centre of the arch is an upright thirteenth-century grave slab. The prevailing opinion is that this Magnus was the third son of Harold II by his first wife, whose mother, Githa, was a Danish princess, and sister of Sweyn, who succeeded Hardicanute. After Harold's defeat his three sons sought refuge in Ireland but launched attacks sporadically on the English coast. They were eventually defeated by Beorn, Earl of Cornwall. The two elder brothers, Godwin and Edmund returned to Denmark and the third, Magnus, is said to be he who is buried in the original Saxon church.
