The nave and the chancel are almost certainly Norman, and prehaps date from the eary 12th century. The simple quoins in bith the nave and chancel are still, visible, and are made of local ironstone and tufa, with larger Ragstone blocks at the base. The walls themselves are of rendered Ragstone rubble, and in the East gable are two round - headed riches. The West end of the nave is now obsured by the modern shed on the North, and by th 19th century bestry on the South. In the South wall of the chancel are traces of an earlier window jamb just East of the early 14th centuy window. It is partly obscured by render, but may date from the 13th century. The tree light East window, though restored externally, probably dates from about the mid 14th century, as does the single lighr trefoil heaed douth chancel window. Both have similar rere-arches inside. On the North side of the chancel is now the well known tomb of Sir Thomas Crawne (1374). Aove it and associated with it is a very fine square headed window. This has been well described and illustrated by Aymer Vallance. The simple rafter-and-collar chancel roof may also date from the 14th.
