Landscape and Archaeological Assessment

Landscape Classification

This sheet represents a coastal downland landscape, characterised by South Downs scarp, river gaps and coastal plain.

Archaeological Landscape

The primary archaeological theme is South Downs routeways, barrow landscapes and coastal/river-mouth settlements. river-gap movement corridors and maritime/coastal plain archaeology

High Visibility Locations

South Downs Ridge, Devil's Dyke / Downs high ground, Lewes Downs

Terrain Archaeology

The terrain is interpreted using hachures. South Downs hachures reveal high points, dry valleys and route corridors very clearly.

Main Geographic Information

Index grid confirms Sheet IX south of Sheet VIII and west of Sheet V. Visible SUSSEX county label, Selsey Bill, English Channel coastline and South Downs terrain support the placement. Bounds remain approximate because graticule labels are faint.

Main Landscape Features

Sheet 9 shows a mixed area of coastal downland South Downs scarp, river gaps and coastal plain . The map is useful for studying early 19th Century historic settlement patterns, Roman road alignments, early archaeological site indentification, how roads, old tracks, lanes and paths, villages, waterways and field systems related to the wider nineteenth-century landscape.

Main Geographic Features

Archaeological Predictions

Archaeological Hotspots

South Downs Ridgeway and Barrow Belt is interpreted as a prehistoric ridgeway / funerary landscape landscape. Lewes Ouse Gap is interpreted as a river-gap settlement and route node landscape. Shoreham Adur Mouth is interpreted as a coastal river-mouth port zone landscape. Brighton Downland Fringe is interpreted as a coastal settlement and downland route zone landscape.

Historic Routes, Crossings and Connections

South Downs Ridgeway Corridor is interpreted as a prehistoric/Roman ridge route. Historic crossing points where roads, trackways or routeways converge on significant water features are widely recognised as archaeological hotspots. Crossing points often acted as gateways within the historic landscape. Because movement was channelled through these locations, archaeological evidence may occur both at the crossing itself and along the routes leading towards it, forming broader zones of archaeological potential rather than isolated sites.Coastal Plain Corridor is interpreted as a coastal Roman/medieval movement corridor. Historic crossing points where roads, trackways or routeways converge on significant water features are widely recognised as archaeological hotspots. Crossing points often acted as gateways within the historic landscape. Because movement was channelled through these locations, archaeological evidence may occur both at the crossing itself and along the routes leading towards it, forming broader zones of archaeological potential rather than isolated sites.

Historic Gateways and Crossing Places

Lewes Ouse Crossing is a river gap / bridge crossing. Shoreham Adur Crossing is a river mouth / bridge crossing. Steyning Adur Valley Crossing is a inland river valley crossing.
