The third restoration took place from 1909 to 1979, supervised by the Reverend Thomas A. Egan and Percy le Clerc, the Inspector of National Monuments at the time. The nave was given a roof and the interior was restored to how it would have appeared in the thirteenth century. It consists of a tessellated quarry tile floor, re-glazed clear glass, and an exposed oak roof. Another aspect of the interior is the rib-vaulted chancel with carved capitals of animals and birds with leaves and plant inclusions. The restorations were done under the liturgical reforms sanctioned by the Second Council of the Vatican.
