The partly coursed flint and ashlar church has a chancel with N organ chamber/vestry, nave with N aisle and S porch, and a W tower. The E wall may survive from the 12thc., but the church was substantially rebuilt in the 14thc. and was rededicated in 1326. The top stage of the tower is 15thc. and the S porch 15thc. or early 16thc. The chancel was rebuilt in 1857 by W. Slater and the chuch was extensively restored in 1875 by R. H. Carpenter. The corbels of the chancel have been described as Norman but they appear to date from the 19thc. The Purbeck marble font is the only Romanesque feature. It probably dates from the first half of the 13thc.

There are six entries in the Domesday Survey relating to Hanging, Little and Steeple Langford. VCH associates one of these with Steeple Langford in which Osulf held the manor in 1066. Waleran the huntsman held it at 1086 and the manor descended to his heirs.

The font, probably dating from the first half of the 13thc. is one of a number of similar fonts found in a group of churches near Salisbury. This group includes Amesbury, Dinton, Downton, Ebbesbourne Wake, Heytesbury (destroyed), Kingston Deverill (removed 1847), Maiden Bradley, Rushall and Stratford sub Castle.

Buckler illustrated the font in the early 19thc. (8: plate 17)
