West Haddon is a village in W central Northamptonshire, 10 miles NW of Northampton on the road to Rugby (the A428). The village was a medieval market town in the Domesday hundred of Alwardsley and clusters around a crossroads on high ground in the hilly landscape, with the church at its centre and the hall site to the S. The nave is tall, with a big Perpendicular clerestorey and aisles with three-bay 13thc. arcades. There are doorways to N and S, the latter 13thc., under an 18thc. porch. The chancel has a 13thc. piscina and a small 13thc. lancet in the S wall, but the E end is Perpendicular. There is a vestry on the N side. The W tower dates from the 14thc. and had a spire which was taken down in 1648. All Saints' contains an important 12thc. font with figure scenes.

In the Domesday Survey, the main holding of 2 hides was possessed by the abbey of Coventry, and there were smaller parcels of 11/2 virgates held by William Peverel and 1 virgate held by Gunfrid de Choques. The church of West Haddon was later given to the Cluniac priory of St Augustine, Daventry by Hugh Poer, grandson of the founder. A market and a fair to be held in the town were granted by King Edward I to the Prior and Convent of Daventry in 1292.

Zarnecki (1951) dated the font c.1120, associating its style with that of the historiated capitals at Southwell Minster. Stone (1955) linked its style to the font at the Cluniac priory of Lenton (Notts) which also depicts scenes from Christ's life, a connection rejected as "not convincing" by Zarnecki (1998). Drake (2002) noted the idiosyncratic treatment of the biblical scenes and considered the Entry into Jerusalem to be unique in English baptismal iconography. His discussion of the iconography is useful.
