The seven South Elmham villages; St James, All Saints, St Nicholas, St Cross, St Margaret, St Michael and St Peter, to which may be added Homersfield, sometimes referred to as South Elmham St Mary, lie in a scattered group between Bungay and Halesworth in NE Suffolk, to the W of the Roman road known as Stone Street. North Elmham (the centre of the see until 1071) is over 30 miles away, to the NW of Norwich, and both apparently took their name from Aethelmaer (bishop of East Anglia 1047-1070) the landholder before the Conquest. This is not certain; Tricker suggests that the name meant villages where elm trees grew. The land here is flat, generally arable and sparsely populated; the villages rarely more than a few houses clustered around the church without shops or pubs.
South Elmham St James consists of a scattering of houses alongside a minor road. A pair of farmhouses mark the ends of the village, and the church is towards the E end. It consists of a nave with a S aisle, chancel and W tower. The nave has a late-12thc. N doorway; all that remains to indicate its early date. The four-bay S aisle was added at the end of the 13thc.; its piers are octagonal with octagonal moulded capitals and chamfered arches. The S doorway is of the same date, as are two of the aisle windows. The remaining aisle window, the N nave windows and the porch are 15thc. On the S side is a rood stair. The chancel is early 13thc., to judge from one lateral window and the S doorway. The piscina is 14thc. and the E window 19thc. in imitation of an early 14thc. intersecting window with cusping. The two-storey tower is tall and unbuttressed; perhaps 12thc. in its lower part but with no diagnostic features. The upper storey has Y-tracery bell-openings (c.1300) and the parapet is decorated with arcading in flushwork. Construction is of flint throughout. The only Romanesque sculpture is on the N doorway and a Purbeck marble font.
