Landscape and Archaeological Assessment

Landscape Classification

This sheet represents a upland valleys and estuary fringe landscape, characterised by Glamorgan and Monmouthshire hachured uplands, river valleys, ridgeways and Severn/Bristol Channel approaches.

Archaeological Landscape

The primary archaeological theme is South Wales upland valley, Roman route, hillfort and estuary-edge landscape. Enhanced prediction from Roman-road, ridgeway, hillfort/enclosure, villa/estate, road-convergence and river-crossing logic.

High Visibility Locations

Glamorgan Upland Ridgeway Belt

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 36 / N° XXXVI visible; Monmouthshire, Gloucestershire, the Forest of Dean, River Wye and the Severn Estuary support placement. Graticule labels are faint or unreadable, so WGS84 bounds are approximate.

Main Landscape Features

Sheet 36 shows a mixed area of upland valleys and estuary fringe Glamorgan and Monmouthshire hachured uplands, river valleys, ridgeways and Severn/Bristol Channel approaches . 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

Glamorgan Upland Ridgeway Belt is interpreted as a upland route, hillfort and beacon landscape landscape. South Wales Valley Crossing Belt is interpreted as a river-valley settlements and crossings landscape. Severn/Bristol Channel Edge is interpreted as a coastal/estuary route and landing zone landscape.

Historic Routes, Crossings and Connections

Glamorgan upland high route is interpreted as a prehistoric/Roman upland 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.Usk/Glamorgan valley route is interpreted as a river-valley Roman route.

Historic Gateways and Crossing Places

South Wales valley crossing cluster is a river valley crossing chain. Bristol Channel landing/crossing fringe is a estuary/coastal access.
