Wonston is a village in the City of Winchester district of Hampshire, 6 miles N of the centre of Winchester and 8 miles SE of Andover. The river Dever runs to the N of the village, parallel with the main street, and the church stands between the two, at the E end of the village centre. It consists of nave with S porch and W tower, A N aisle and a chancel with a N vestry. Construction is of flint rubble, mostly rendered, with stone dressings and tiled roofs. Romanesque features described here are the S doorway and the chancel arch.

According to the Domesday Survey, the Bishop of Winchester held Wonston in 1086, and always had. It was assessed at 7 hides in 1086 and the church is recorded at that time. It remained with the bishop until 1541, when it was granted to the dean and chapter of the cathedral, who still hold it. The nave and chancel of the present church were built in the later 12thc., the tower was built in the 15thc., the N aisle was added in 1872 and the vestry was added after a fire in 1908, at the same time as the porch.

The doorway and chancel arch are clearly closely related, although the doorway is stylistically earlier with its simpler imposts and trumpet-scalloped label stops. Both features have curved profiles in their orders, and while the chancel arch relies heavily on lily (fleur-de-lys) foliage it also references the scalloped capital in the S capital of the 1st order. They must have been carved in the last 20 years of the 12th century.

Bullen and Pevsner relate the carving of the chancel arch to work in the nave arcades at Deerhurst (Gloucs), and suggest that work of this quality indicates a connection to Winchester cathedral.
