There is scant evidence of significant prehistoric habitation in South Newton. There has been a settlement in the village since
Saxon times and South Newton is largely a 10th-century estate which stretched from the River Wylye to the ridge of the hills to the north-east. The village originated at about the same time as its three neighbours Stoford, Chilhampton and Little Wishford, each village having a strip of land down to the river and up onto the downland of the drainage area. In 1086 the
Domesday survey recorded 42 households at
Newenton or
Newentone. The ancient parish had a detached part at North Ugford, on the other side of the Wylye and bounded to the south by the
Nadder. This area (now farmland, and the hamlet of Ugford on the A30) was by 1884 divided between
Burcombe and
Wilton parishes. The
railway between Salisbury and Westbury, completed in 1856, runs on the opposite side of the Wylye.
Wishford station at
Great Wishford was about north-west of South Newton. The station was closed in 1955 but the railway remains open as part of the
Wessex Main Line. ==Parish church==
