All Saints is a 12th-century parish church given Grade 1 listed status in 1966. It is stone built with a west tower, nave with north and south aisles and clerestory lighting, a south porch and chancel. The tower, nave and aisles are battlemented, and the chancel has a simple parapet.
The building is mainly of the Decorated Gothic style which lasted from the late 13th to late 14th centuries but the south porch and some earlier piers and arches on the south side are in the plainer Norman style. The tower was built in the early 13th-century with a battlement added later.
The south aisle is divided from the nave by two pointed arches supported by a massive circular pillar similarly there are two pointed arches separating the north aisle. However, these rise higher than the ones on the opposite side. There is a piscina at the east end of the south aisle and a stained-glass window depicting the Annunciation which indicates that there was a lady chapel there at one time.
Interesting features include remnants of distemper mediaeval wall paintings and some unusual carving possibly from designs brought home by a crusader, a double headed dragon on the south side of the pillar supporting the arches of the south aisle and a slab on one of the piers depicting a serpent and two strange animals.
The chancel floor is paved with black and white marble at the “cost of Sir H. Andrewes bart. at the request of his daughter Margaret” and on many of the white squares there are memorials to members of the Andrewes family who were buried there. Near the altar there is an inscription to Elizabeth, Lady Leigh, Baroness of Stonly, who died in 1678. On a north wall of the chancel there is a tablet headed with the arms and crest of the Chandflower family representing a lady in Elizabethan dress kneeling at an altar with a youth behind her and two babies in a cradle. Other memorials refer to the families of Dobinson and Forster and in the north aisle there is a marble monument to Henry Uthwatt and his wife Frances, daughter of Sir J. Chester, Bart who died in 1800.
The six clerestory windows are pointed, of two lights each with glazed with plain glass. Ten windows are glazed with stained glass, most of them in the mid to late 1800s.
The firm of Michael O’Connor and Sons was responsible for the east window which has four lights with quatrefoil heads and two windows with two lights each on the south side of the chancel. The one of The Virgin Mary holding Christ and St Elizabeth holding John the Baptist is dated 1869. Ward and Hughes glazed the windows on the other side of the chancel in 1883 and 1888 and Henry Hughes did the windows at the east end of the south aisle and one in the north wall of the north aisle in his own name. James Powell and Sons was responsible for the east end of the north aisle, the west window of the south aisle is also of stained glass by an unknown artist and finally Joseph Ambrose Nuttgens, a well-respected modern stained-glass artist made the 6th Day of Creation window in 1986.
