Built in the 12th century, St James' Church has been recognised as the main church in Cherhill for around 900 years. The church, which was dedicated to St James in 1405, consists of a chancel and nave dating back to the 12th century, as well as a south aisle, south porch, west tower and north vestry. The aisle and tower were added in the late 15th to early 16th century and an east window was added in the early 18th century. A Gothic west gallery was added in 1840 and the church was restored in 1863 to designs by S.B.Gabriel by Mullings of Devizes who charged £62 for the chancel roof and £550 for other services. The church was later reopened on the 22nd November 1863.
A number of registers from the church still survive today. Registers of baptisms survive from 1690, registers of marriages from 1709 and registers of burials from 1708. Apart from registers currently in use at the church these are held in the Wiltshire & Swindon History Centre at Chippenham.
The church contains three bells, one of which was cast in Bristol in 1450. The treble bell was replaced in 1619 by a bell cast by Richard or Roger Purdue. In 1641 the tenor bell was replaced by a bell cast at Warminster by John Lott and recast at Whitechapel in 1987.
