Wixoe is a village in the Stour Valley on the Essex border E of Haverhill. St Leonard's has an aisleless nave and chancel in one, sharing a single roof and with no chancel arch. The nave walls are slightly thicker than the chancel (visible on the interior by a ridge in the wall at the position of the chancel step), and the mortar used in the flint cladding is yellower in the nave. There is a 19thc. vestry on the N side of the chancel. The nave has a modern timber west bell turret. The N and S nave doorways are 12thc., the N blocked and overgrown; the S protected by a 19thc. timber porch. The S chancel doorway is 19thc.

Wixoe was held by Thegn Godwin in the time of Edward the Confessor. In 1087 it was held by Ralph Baynard and consisted of ploughland, woodland for pigs, sheep, and cattle, meadow, a mill, beehives and a church with five acres of land.

Stour Valley Group, i.e. Clare, Poslingford, Cavendish, Stoke by Clare and Wixoe.

The rather plain S doorway has similarities to that at Depden, in the angle-tucked cushion capitals and the form of the chevron roll, set back from the angle of the order without any elaborate edge treatment.
