Before the Conquest the principal manor of Wallop was held by Countess Gueda or Gytha from Earl Godwin. It was granted to Amesbury Abbey by Henry II in 1177.
In 1086 Wallop was a relatively large settlement with 91 households, a church and a chapel. The church may have been dependent on the old minster at Mottisfont (Gem & Tudor-Craig 1981, 116). It was granted to York Minster by Henry I in 1133.
The W tower was rebuilt following collapse in 1704. Much of the N aisle was rebuilt in brick in 1752. The chancel had been extended to its existing length by 1845, when it was rebuilt in a neo-Norman style. At the same time the W gallery was removed to reveal the tower arch, the windows were reglazed, the nave was repewed and refloored, and a new font was installed. The ‘old broken’ font was ‘ingeniously hidden in one of the high pews under the gallery’ (Salisbury & Winchester Journal, 19 July 1845, 3).
The compound pier, pier 1, of the S nave arcade was completely rebuilt in 1978 (Gem & Tudor-Craig 1981, 119).
