The manor of Empshott (Hibesete) was held by Geoffrey Marescal, or Geoffrey de Venuz, in 1086. It was still in the hands of the Venuz family in the 13thc.
No church was mentioned in 1086. In the mid-12thc the advowson was granted to Southwick Priory, Portchester, which was founded in 1133. Confirmation of this by Papal Bull reveals that a chapel (‘the chapel of Ymbesieta’) existed by 1181 at the latest. On the evidence of the architecture, this was replaced by a church c.1200. The church, dedicated to St Lawrence, remained attached to Southwick Priory until the Dissolution.
The building presumably fell into disrepair prior to its renovation, supposedly at the behest of Lancelot Andrews, Bishop of Winchester, c.1624-26. As well as providing new (dated) furnishings, this campaign may have involved the addition of the W porch and W tower, the clearance of the chapels N and S of the chancel, and the reduction of the aisles. A sketch of c.1780 shows the church from the SE, with the chancel lit by a large mullion and transom E window (illustration from church guidebook), potentially of c.1624-26 date.
In 1838 and 1859 the church underwent repairs, but these soon failed. More significant work was commissioned c.1867-68. The W tower was rebuilt (to designs by a Mr Pusey, presumably either Frederick or William Puzey, carpenters in the nearby village of East Tisted), the nave and chancel were re-roofed, the chancel was largely rebuilt with buttressing, and a vestry was added.
