Nave of c.1200 or slightly later, heightened 15thc. with a late 13thc. chancel and 14thc. transepts. Carved S nave doorway contemporary with nave. The lead font from the same period is not described.

A church at Childrey is mentioned in a document of 996 and again in DS on the manor held by Thurstan, son of Rolf (two other manors recorded at Childrey). This manor held by William de Frethorne in 1166, and remained in that family until 1357 when it was conveyed to Edmund de Chelrey.

VCH and the Childrey guide associate the building of the c.1200 church with the patronage of William de Frethorne and suggest that it was completed not later than the appointment of William's son John as rector in 1207. The date seems about right but this may simply be coincidence. The lead font dates from the same time as the church, as does another at Long Wittenham. There is a third lead font at Woolstone that is smaller and difficult to date. Despite all being of lead, they are unrelated in design; Childrey's font is the only figural one.
