Around 3600BC. Barkdale Camp [Map] is a Causewayed Enclosure on the South Downs in West Sussex. In 1929, John Ryle noticed the earthworks at the site, and in 1930 E. Cecil Curwen and G.P. Burstow surveyed the site, and identified an interrupted ditch in the northern part of the site. In 1958 Veronica Seton-Williams began a series of excavations at Barkhale Camp; she dug for four seasons. Seton-Williams excavated six of the thirteen ditch segments that Curwen had identified

Burnham Causewayed Enclosure [Map] was a causewayed enclosure now more or less disappeared.

The River Medway rises near Turners Hill [Map] from where it flows through Wood Weir Reservoir [Map], past Forest Row [Map], between Hartwell [Map] and Hartfield [Map], after which it is joined by the River Grom, past Ashurst, Kent [Map], Hedge Barton, Kent [Map], Penshurst, Kent [Map], under Ensfield Bridge, Kent [Map], through Tonbridge, Kent [Map], past East Peckham, Surrey [Map], Nettlestead, Kent [Map], under Teston Bridge, Kent [Map], under Kettle Bridge, Kent [Map] and East Farleigh Bridge, Kent [Map], through Maidstone, Kent [Map].

After Maidstone the river flows past Aylesford, Kent [Map], Burnham Causewayed Enclosure [Map] and Wouldham, Kent [Map] to Rochester, Kent [Map].

Around 3600BC. Combe Hill [Map] is a causewayed enclosure on the northern edge of the South Downs in Sussex. The enclosure has been excavated twice: in 1949, by Reginald Musson, and in 1962, by Veronica Seton-Williams. Musson found a large quantity of Ebbsfleet Ware pottery in one of the ditches.

Around 3600BC. The The Trundle [Map] is a causewayed enclosure that became an Iron Age Hill Fort in West Sussex. It rises above the neighbouring hills and so is clearly visible from all sides having an elevation of 206m. The causewayed enclosure consists of at least four circular or partly circular ditches enclosing 9300m².

Around 3600BC. Whitehawk Camp [Map] is a causewayed enclosure near Brighton in Sussex. In 1929 R. P. Ross Williamson and E. Cecil Curwen undertook atn excavation at Whitehawk Camp. In 1930, the archaeologist E. Cecil Curwen identified sixteen sites that were definitely or probably Neolithic causewayed enclosures.

The Iron-Age Hill Fort consists of a well-defined bank and ditch, with a smaller outer bank, in an irregular nine-sided polygon. There are two gaps, at the east-northeast and west-southwest edges, indicating entrances. The depth of the ditch and the height of the bank vary, with the highest point reaching 5.5 m (6.0 yd) above the bottom of the ditch.
