The church consists of nave with side aisles, chancel, W tower, and S porch dating primarily from the 13thc. through the 15thc. centuries. Restoration of ceiling and chancel area undertaken in 1902-3. The S porch doorway has Romanesque nook shafts and capitals.

The Domesday Survey records both a church and a priest in Long Bennington. In 1086 the primary landholder of the village was Count Alan.

Though Pevsner calls the nook-shafts 'Norman' it is doubtful that they are of the same piece with the Romanesque capitals. The diameter of the nook-shafts is smaller than the capital neckings and make for an ill fit between shaft and capital. That the imposts of the capitals and those of the first order are separate is clear from the fact that they are not made of the same piece of stone (clear mortar joint between them) and the scale of the continuous hollow chamfer changes between these architectural elements.
