St George's Church......this ancient and beautiful parish church of West Grinstead stands on the northern bank of the river Adur...now a sluggish stream at this inland point in the Sussex Weald....in a remote and secluded spot at the end of a lane half a mile from the main road. There is known to have been a Saxon settlement in the area before the Viking and Norman invasions. By the eleventh century, with the river Adur then providing essential means of transport and trade, West Grinstead had grown and become more important. The earliest part of the church, as we see it today, was built around 1100. About the year 1200 the tower was begun....a fine example of a Sussex Cap (a low “flat” spire), now topped with a steeple clad with oak shingles.
Partridge Green was, and still is, part of the parish of West Grinstead, although it has had its own church since the 19th century, as it grew after the introduction of the railway.
