ALLT-Y-BELA MANOR

Identity: likely — The registry name corresponds to the historic Allt-y-Bela/Allt-y-bella house in Llangwm, Monmouthshire, at SO 411 005. The building is a documented late-medieval manorial or gentry house, associated with Roger Edwards in the early seventeenth century. The supplied 1570 survey lead is catalogued by the National Library of Wales under the Cefn Mabli papers, but the accessible catalogue data does not expose the survey's territorial description or map.
Representative point: 51.7008, -2.8536
Basis: documented_manor_house — Allt-y-bella, a Grade II* listed late-medieval house at Llangwm, Monmouthshire; listed coordinates approximately 51.7008, -2.8536, OS grid SO411005.
Point confidence: high
Boundary status: representative_point_only
Boundary period:
Boundary confidence: none
Boundary basis: No reliable accessible source was found that supplies or clearly reconstructs the historical manorial perimeter. The modern property website describes approximately 165 acres of reunited surrounding estate, but this is a modern estate/conservation holding and cannot safely be treated as the historical manor boundary. The 1570 survey reference is evidence that relevant historical land records survive, but its mapped extent was not available from the accessible catalogue record.

Warnings / uncertainty:
- The identification is strong geographically but the accessible evidence does not independently prove the legal extent of the manor named in the registry record.
- Do not substitute Llangwm parish, Llantrisant Fawr community, a modern property boundary, or the present 165-acre estate for the historical manorial territory.
- The supplied 1570 survey should be examined directly through the National Library of Wales or a digitised archival image before attempting polygon reconstruction.
