ARWYSTLI MANOR

Identity: confirmed — The National Archives record F236291 identifies Arwystli Manor in Montgomeryshire. The National Library of Wales catalogue independently describes the lordship or manor of Arwystli, its associated title deeds, rentals and properties in Montgomeryshire parishes including Llandinam, Llanidloes, Llanllwchaearn, Llanwnog, Penegoes and Trefeglwys. The supplied survey, rental, court-roll and enclosure references are consistent with this same large historical lordship/manor rather than a modern administrative unit.
Representative point: 52.5001, -3.5291
Basis: documented_manor_house — Talgarth house, near Trefeglwys, is a surviving documented manor house traditionally identified as the seat of the Lords of Arwystli. It is the best surviving precise manorial-site candidate located within the Arwystli lordship, although the identification is traditional rather than demonstrated by a surviving contemporary plan.
Point confidence: medium
Boundary status: representative_point_only
Boundary period: Historical Arwystli lordship/manor, especially the sixteenth to nineteenth centuries
Boundary confidence: none
Boundary basis: The evidence establishes a substantial and territorially distributed lordship/manor, not a single compact modern parish boundary. Archival descriptions place Arwystli-related properties across numerous Montgomeryshire parishes, while historical landscape research distinguishes the former commotes or divisions of Arwystli Uwchcoed and Arwystli Iscoed, with manorial centres at or associated with Talgarth and Pen-prys/Caersws and later administrative importance at Llanidloes. The supplied references include surveys, rentals, court rolls, enclosure material, maps and notes on boundaries, but the accessible evidence does not provide a source-supplied perimeter or enough explicit boundary calls to reconstruct a defensible polygon. A modern parish, community, hundred or county boundary would not be an acceptable substitute.

- Clwyd-Powys Archaeological Trust: Clywedog Valley administrative landscape: https://heneb.org.uk/archive/cpat/projects/longer/histland/clywed/clyadm.htm — Explains that Talgarth became the manorial centre of Arwystli Uwchcoed and that the historic Arwystli lordship was later administered through upper and lower divisions corresponding broadly to Arwystli Uwchcoed and Iscoed.
- Clwyd-Powys Archaeological Trust: Pen-prys, Llys, PRN 142444: https://archwilio.org.uk/arch/query/page.php?watprn=CPAT142444 — Identifies Pen-prys near Caersws as the manorial centre or court of Arwystli Iscoed in the late thirteenth century, demonstrating that the historical territorial organization had more than one manorial centre.
Warnings / uncertainty:
- The exact registry record is identifiable, but Arwystli was a historically complex lordship whose divisions and administrative centres changed over time.
- Talgarth is a documented surviving manor-house candidate and is safe as a representative point, but it should not be interpreted as the geometric centre or complete territorial extent of the manor.
- No defensible historical perimeter polygon was found in the accessible sources. Do not inject a parish, civil-community, hundred, county, modern estate or postcode boundary as the manor boundary.
- The manor's later estate holdings and the medieval or Tudor lordship extent should not automatically be treated as identical.
