The Sussex Greensand Way is a Roman road linking the London to Lewes Way at Barcombe Mills to Stane Street at Hardham. The road, which has almost entirely fallen out of use, follows the free draining ridge of greensand which lies north of the South Downs. It is a planned route rather than a Romanised iron age track, following a few straight alignments without any steep gradients, which linked various north-south roads and tracks. A number of important Roman villas and their farming estates were linked by the road. It is not known at what time during the Roman period the road was built.
