Bullington is in rolling woodland and sheep pasture in central Hampshire, 7 miles N of Winchester, and is one of a chain of villages than runs along the valley of the river Dever, many of which form the present benefice. This dispersed village runs for a mile along the river, with Lower Bullington to the W and Upper Bullington to the E. 1 mile N of the village is the Iron Age hillfort of Tidbury Ring. The A34 trunk road runs from N to S between the two, and the A303 from E to W, the two intersecting immediately N of the village. The church is in Lower Bullington, in wooded pasture land on the S bank of the river Dever.
It consists of a flint nave and chancel in one, with a 19thc neo-Romanesque S nave doorway set under a flint and timber 19thc porch and a blocked 12thc N nave doorway without a porch. There are plain 12thc lancets on the lateral walls of the nave towards the W end. The 13thc chancel has a N vestry and the church has a W tower of brick with a tiled pyramid roof. There was a restoration in 1871 and Pevsner suggests that the tower may date from that time. The only Romanesque feature recorded here is the N nave doorway.
