Of the aisleless, cruciform church, the upper part of the tower survives with its four (reduced) internal openings and Romanesque windows. Aisles were added to the nave c.1200 both N and S, but the former was later dismantled. The chancel was remodelled in the 13thc and again in 1835. The only Romanesque sculpture at the site is the loose voussoir recorded here, seen in 1984.

Burnham Overy, an important royal manor, lies in the hundred of Gallow, territory of which Godric had charge at the time of the Domesday survey of 1086. The majority of the other geographically concentrated group of north-west Norfolk parishes called the Burnhams lie in the hundred of Brothercross. In the mid-12thc, the church belonged to the canons of Walsingham priory, Norfolk, having been given to them by William Le Veautre.

The striations on the voussoir may be the result of weathering; weathering has produced a similar effect on some of the ashlar dressings on the exterior of the building.
