Landscape and Archaeological Assessment

Landscape Classification

This sheet represents a coastal sound and estuary landscape, characterised by Plymouth Sound, Tamar/Hamoaze, coastal headlands, anchorages and route convergence.

Archaeological Landscape

The primary archaeological theme is Plymouth Sound maritime, estuarine crossing and coastal promontory landscape. Enhanced prediction from Roman-road, ridgeway, hillfort/enclosure, villa/estate, road-convergence and river-crossing logic.

High Visibility Locations

Plymouth Sound Harbour Core

Terrain Archaeology

The terrain is interpreted using hachures. Relief is represented by hachures, allowing inference of ridgeways, high points, spur ends, valley approaches and likely route/crossing logic.

Main Geographic Information

Main Landscape Features

Sheet 24 shows a mixed area of coastal sound and estuary Plymouth Sound, Tamar/Hamoaze, coastal headlands, anchorages and route convergence . 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

Plymouth Sound Harbour Core is interpreted as a harbour, anchorage and naval/port archaeology landscape. Tamar/Hamoaze Crossing Belt is interpreted as a estuarine crossing and route convergence landscape. Rame Head Promontory Zone is interpreted as a coastal lookout/enclosure/beacon landscape landscape.

Historic Routes, Crossings and Connections

Tamar-Plymouth-South Devon corridor is interpreted as a estuarine/coastal 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.Rame-Cawsand-Whitsand coastal route is interpreted as a coastal headland route.

Historic Gateways and Crossing Places

Tamar/Hamoaze crossing is a major estuary crossing. Plymouth Sound landing/access is a harbour landing/crossing.
