The church in Hullavington and the church in Surrendell followed the path of the manor house in being passed from the Mortimer family to the abbey St Victor-en-Caux in the early 12th century and later to the Crown and then Eton College in 1443. A vicarage was ordained by 1240 and possibly before this the churches were run by the abbey's monks.
Hullavington church was known as St Mary Magdalene's from 1408 but was latterly dedicated to St Mary (the virgin) from 1763. The nave and chancel are 12th century, the adjoining chapel and porch 13th century and the original tower was built in the 14th century. However, during 1871-2 the church underwent major redesigning by A W Bloomfield and the tower was replaced and many areas of the church restored. In 1917 its 14th and 15th century wooden screen was removed (a new screen was later erected in honour of the men of Hullavington who died in WW1). Despite these modifications, the 15th century benchends can still be seen today along with one of the original 13th century windows (north aisle, west window). A 15th century detailed piece of embroidery thought to have once formed part of a chasuble can also be viewed.
