A Norman Church on the present site is first mentioned 1106, but only the North and
South doors and font remain, reused in a subsequent construction. The present chancel
belongs to the decorated period and was built around 1340, with a south aisle being
added some decades later.
With the exception of the chancel the Church was rebuilt
in the perpendicular style from just before 1500 until about 1540 when the tower
with the pinnacles was completed. In 1848 the Church was restored and improved under
the supervision of Francis Niblett. The walls of the chancel were raised and the
roof replaced. The tall box pews were replaced with the current pews but utilising
wood salvaged from the old pews, with the addition of machined ends and rails.
An
illustrated guide to the church is available to those who visit for a small consideration.
