A squat church composed of a W tower (13thc.), a nave with a N aisle (14thc.) and a chancel (14thc.). There is no obvious 12thc. work, although the S wall of the nave may be Norman.

The first documentary mention of Rudgwick occurred in 1210, and so both church and font are likely to date from the early 13thc.

The church was restored by J. P. Harrison in 1845-47.

Although Godfrey dated this font to the late 12thc., it may incorporate elements of different dates. The use of ogees in the upper plinth suggests that this element was recut or replaced in the early 14thc., at the earliest. The lower plinth, angle columns and bowl may date from the modern period, possibly as part of a church restoration programme. The arcading on the bowl belongs to a regional tradition which originated in the 12thc. but lingered into the 13thc.
