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 | Probably built by Llywelyn ap Iorwerth, prince of Gwynedd, between 1215 and 1230 (an identified ruling lord), with a curtain wall carrying three integral towers, a central square tower, a D-shaped tower and a rock-cut defensive ditch providing active defence; Cadw cites importance for medieval settlement and defence — both halves met. |
