[2] The original Holy Rood Church was of Early English style and made up of a nave, chancel, south aisle, north porch and west tower.

By the mid 19th-century, the church had fallen into a dilapidated state, including suffering from damp and the encroachment of ivy.

The three bells from the tower had also been placed in the unused south aisle, along with the remains of the broken stocks and wheels which had been used to hang them.

The church's poor condition had long been a concern to the clergy and a committee was formed around 1858 by the Rural dean, Rev.

[5] The diocesan architect drew up plans for a major restoration scheme but this was deemed too costly and by the end of 1858, the committee opted for Rev.

Joseph Weld, the lord of the manor and chief landowner, requested the church's tower be retained.

[5] The majority of required capital (£427) was received from clergy and gentry in the surrounding area, while £100 was raised within the parish from a church rate contributed by eight ratepayers.

[3][4] The Salisbury Diocesan Church Building Association and Incorporated Society each granted £50 towards the cost,[7][6] and with an additional £35 in voluntary subscriptions, a total of £662 was raised.

As part of the tower's restoration, buttresses and a pyramidal roof were added, and its three bells rehung.

In 1980, the Coombe Keynes Trust was formed, presided by Sir Joseph William Weld, with the key objective of "promot[ing] the restoration and permanent preservation" of the church for the public.

[14] It is made up of a nave, chancel, north porch and west tower with a vestry formed in its base.

[2] The church's pulpit of Bath stone, communion table, prayer desk and lectern were all contemporary fittings with the 1860–61 work.

In recent years, the chalice was returned to the parochial church council of Wool and East Stoke, and is now on loan to the Dorset Museum.
