White Castle
Y Castell Gwyn
Which definitions does it satisfy?
This dataset does not record whether something “is a castle”. It records a verdict against each named definition, with the reasoning that produced it.
| Definition | Verdict | Basis |
|---|---|---|
| Fortified residence | contested | The report cuts both ways. It describes a lordly castle with a private appartment, a chapel and a hall and heavy active defence (a twin round-towered gatehouse with portcullis and drawbridge, mural round towers, arrowslits and an exceptionally deep, steep-sided moat) — yet states that 'the sole purpose of White Castle was military', that it was garrisoned by troops and was austere and functional, so the private-residence half is argued against by the designation itself. |

Disputed
One reading takes White Castle as a fortified lordly residence — a Marcher castle (William Fitz Osbern, later the crown under Lord Edward) with a private appartment, a chapel and a hall. The other follows Cadw's own statement that 'the sole purpose of White Castle was military', a garrisoned, austere and functional work whose residential provision was minimal (the hall only in timber, a single private appartment), pulling it away from the residence half.

Notes
Upgraded to an assessed record from Cadw's full report (MM006). fortified_residence assessed 'contested' because the report simultaneously documents residential fabric (private appartment, chapel, hall) and declares a sole military purpose. state_fortification left unassessed — that band is for gunpowder-age state works, whereas the original purpose here was a medieval Marcher/crown lordship castle; its earth-and-timber origins are part of that lordly castle, not a separate enclosure_fortification.
