The earliest work is found at the SW end and appears to have been built under the influence of the newly-completed work at the Canterbury Cathedral choir of 1175-80. The piers vary in shape with round, octagonal and quatrefoil forms all in evidence and with a wide variety of foliage decoration which demonstrate the transition from Norman, to work of the C13. The N arcade has double-chamfered pointed arches whereas the S one has moulded arches. The N arcade is slightly later than the S one. The nave seems to have been extended eastwards in the early C14 with the break in the two schemes evident in the foliage of the easternmost S pier where the W half represents the original respond and the E part belongs to the extension. On the N the two easternmost arches are C14. The Perpendicular work, so evident externally, is found in the tower arch, with three orders of shafts and the two-bay chancel arcades with their typical piers of four shafts and four hollows. On the second floor of the vestry of 1513 is the Cranston Library (see History below).
