Landscape and Archaeological Assessment

Landscape Classification

This sheet represents a coastal upland landscape landscape, characterised by Cardigan Bay coast with dissected inland river valleys and upland routeways.

Archaeological Landscape

The primary archaeological theme is Cardigan Bay harbour, Teifi river crossing, coastal route and upland enclosure landscape. Enhanced prediction from Roman-road, ridgeway, hillfort/enclosure, villa/estate, road-convergence, coastal, marsh-edge and river-crossing logic.

High Visibility Locations

Teifi Valley Route Belt, Cardigan Coastal Harbour Zone

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 LVII / N° LVII is visible in the upper-right margin and the sheet number 57 is visible at lower-left. Large county lettering is interpreted as CARDIGANSHIRE across the lower/coastal half with adjacent Montgomeryshire and Radnorshire borderlands inland. Bounds are reconstructed from sheet-index geometry, adjacent Sheet LVI relationship, Cardigan Bay coastline, upland relief and identifiable settlement controls; graticule labels are faint.

Main Landscape Features

Sheet 57 shows a mixed area of coastal upland landscape Cardigan Bay coast with dissected inland river valleys and upland 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

Teifi Valley Route Belt is interpreted as a riverine settlement, bridge/ford and Roman-medieval route potential landscape. Cardigan Coastal Harbour Zone is interpreted as a harbour, coastal trade and estuary settlement potential landscape. Inland Cardigan Upland Ridge Belt is interpreted as a ridgeway and defended enclosure potential landscape.

Historic Routes, Crossings and Connections

Cardigan-Lampeter inland corridor 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.Cardigan Bay coastal route is interpreted as a coastal route.

Historic Gateways and Crossing Places

Cardigan Teifi crossing is a river/estuary crossing. Lampeter valley crossing is a river crossing.
