Castell Gwallter
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 | yes | Assessed from Cadw full report CD005. Active defence: a flat-topped motte (32–33m across, 4.5m high) that "would have been crowned by a great timber tower, with a strong breastwork on the counterscarp", encircled by an 8m-wide U-shaped ditch and counterscarp bank, plus a defended bailey. Residence: the bailey "would have been the site of the lordly hall"; the site was the caput of the lordship of Geneu'r-glyn, established by the Anglo-Normans c.1110. Both halves met. |

Notes
Upgraded to assessed against Cadw full report CD005 (sig-20260722-report-cd005). The report explicitly identifies both halves — a motte crowned by a great timber tower with a counterscarp breastwork and a defended bailey (defence), and a bailey that "would have been the site of the lordly hall", the caput of the lordship of Geneu'r-glyn established by the Anglo-Normans c.1110 (lordly residence) — supporting fortified_residence: yes. Destroyed 1135, last recorded 1153. Other bands OMITTED: the report does not speak to them, and as an obscure destroyed earthwork popular_castle is left unassessed. Confidence medium.
