From the outside, it looks like a simple one-room church from about 1220, with lancet windows and a little spire at the west end.
Step inside and you are instantly taken forward to about 1700, when James Butler, the local landowner, refurnished the interior in a simple but elegant English baroque style.
Overhead, the medieval single-frame roof extends from one end to the other, creating an illusion of length. It must have seemed even longer before the 18th century carpenters inserted the wooden chancel screen with three arches on slim columns.The semicircular space under the roof, called a tympanum, is exuberantly painted with the arms of Queen Anne, with drapery swirling about. In the chancel, the communion rails were given elegant barley-twist balusters.
Warminghurst sits in the middle of the South Downs with only a farmhouse for company, and is now cared for by the Churches Conservation Trust. The upside of this is that nobody will now be tempted to meddle with this magical building.
