The remains of an 11thc. nave, devoid of sculptural detail, are detectable at the W end of the church. The aisles were addedc.1200, and the W tower, clerestorey and chancel slightly later, in the 13thc.

The arcade capitals are the sole surviving sculptures in the church which may belong to the 12thc., but a drawing (NMR, unattributed and undated - possibly from Gentleman's Mag.) of a carved bowl or block (a mortar?), apparently early 12thc., is assigned to Wisborough Green. Local archaeological society does not know its whereabouts.
