Landscape and Archaeological Assessment

Landscape Classification

This sheet represents a coastal estuary and bay landscape, characterised by Fowey, Looe and St Austell coastal inlets, river crossings and coastal routeways.

Archaeological Landscape

The primary archaeological theme is South Cornwall estuary, harbour, river crossing and coastal route archaeology. Enhanced prediction from Roman-road, ridgeway, hillfort/enclosure, villa/estate, road-convergence and river-crossing logic.

High Visibility Locations

Fowey Estuary 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

Sheet number XXXI is visible in the upper-right and lower-left margins. South Devon coastal geography is strongly identifiable; Cornwall is represented by the western side of Plymouth Sound / Rame peninsula. Graticule labels are not legible enough to read directly.

Main Landscape Features

Sheet 31 shows a mixed area of coastal estuary and bay Fowey, Looe and St Austell coastal inlets, river crossings and coastal routeways . 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

Fowey Estuary Core is interpreted as a estuary harbour, river crossing and route node landscape. Looe River-Mouth Zone is interpreted as a coastal river-mouth settlement and crossing landscape. St Austell Bay Coastal Belt is interpreted as a landing/coastal settlement and route landscape landscape.

Historic Routes, Crossings and Connections

South Cornwall coastal route is interpreted as a coastal Roman/medieval route candidate. 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.Fowey-Lostwithiel inland route is interpreted as a river-valley 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.

Historic Gateways and Crossing Places

Fowey estuary crossing/access is a estuary crossing/landing. Looe river-mouth crossing is a river-mouth crossing.
