The Domesday Book of 1086 records a church in the village then called "Cilletone". It is uncertain whether any part of this earlier building was incorporated into the present church, which is believed to date from the first half of the 12th century; but Ian Nairn suggested that the walls of the nave and chancel are "probably 11th-century", and the Saxon-era building almost certainly occupied the same site. The three-bay south aisle was added around 1200, and the chancel arch is of a similar age. A chantry chapel was added in the early 13th century, and another chapel on the south side of the chancel was built a century later. A spire was built in 1602.
