The church building itself is one of the gems of Somerset and owes a great deal to the Sanford family who in the past furnished it with many of its present day the art treasures.
The manor was granted to the Bishop of Winchester in 737 AD, so it is likely that there was some form of a church here at that time. A church in Nynehead is mentioned in the Domesday Book of 1068. By a charter dated 1091, William, Count of Mortain, founder of the Montacute Priory, granted to the monks of Montacute the manor and the church of Nynehead. It was the only Cluniac Order in the county, an order that was developed from Cluny in Burgundy.
In the early 19th century a carved stone head was found while some restoration of the church was in progress, so this would indicate that the present church was built from the remains of a former building. The church building is built mostly of local red Permo-Triassic rock, (a form of sandstone) mixed with various other types of stone and is of a perpendicular style.
