The Church of St Mary and All Saints dates from the 13th century. A church probably existed on this site in Anglo-Saxon times. There are three Anglo-Saxon crosses in the churchyard. The "Church of St Mary held in Wallei" was mentioned in the Domesday Book of 1086. Most of the present church was built in the 13th century, replacing a simpler structure which likely had an aisleless nave and chancel. The tower was added in the late 15th century. A porch was added to the south of the building in 1844, and one to the north in 1909.
