Landscape and Archaeological Assessment

Landscape Classification

This sheet represents a coastal bay and promontory landscape, characterised by Mount's Bay, Land's End, Penzance harbour, Lizard fringe and granite/upland coastal routeways.

Archaeological Landscape

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

High Visibility Locations

Mount's Bay Maritime 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 33 / N° XXXIII visible. The mapped land covers western Cornwall, including the Land's End peninsula, St Ives Bay, and Mount's Bay. Graticule labels are faint, so WGS84 bounds are reconstructed rather than directly read.

Main Landscape Features

Sheet 33 shows a mixed area of coastal bay and promontory Mount's Bay, Land's End, Penzance harbour, Lizard fringe and granite/upland 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

Mount's Bay Maritime Core is interpreted as a harbour, tidal island and coastal settlement landscape landscape. Land's End Promontory Belt is interpreted as a cliff-top enclosure and beacon landscape landscape. West Cornwall Upland Edge is interpreted as a prehistoric upland and routeway landscape landscape.

Historic Routes, Crossings and Connections

Penzance-Land's End coastal route is interpreted as a coastal/promontory 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.Mount's Bay-Helston route is interpreted as a coastal-to-inland route.

Historic Gateways and Crossing Places

Penzance/Newlyn harbour access is a harbour access/crossing. St Michael's Mount tidal access is a tidal causeway/access.
