There are many sites of historical interest in and around Findon, including the magnificient hill fort of Cissbury Ring , and Neolithic flint mines. This site also includes, among other things, information about Nepcote, Findon Place, and the history of the now demolished windmill. Cretaceous sedimentary rocks subjected to subsequent Tertiary Earth movements dominate the scene in Sussex. There are in addition some small pockets of Jurassic deposits. The chalk is soft and crumbly, but contains layers of flint.
Flint occurs in the form of rounded nodules and is very hard.
After the Cretaceous Period during the Tertiary there was a period of mountain building known as the Alpine Orogeny. This began some 30 million years ago and as a result the Cretaceous sediments of Southeast England were subjected to the inexorable forces of Plate Tectonics . This lead to a syncline which is now the Thames Basin, and a corresponding anticline, which encompasses most of Kent, Surrey and Sussex. Weathering and erosion however, have removed the chalk, and other sediments to reveal the underlying deposits which form the Weald. The original chalk covering is now found only at the edges of the anticline, in the form of the North and South Downs.
