Castell Allt Craig-Arth
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 CD092. The report securely classifies the monument as a motte-and-bailey — a timber-castle type explicitly within this band. Active defence: an oval motte ~8m high defended on three sides by steep slopes and on the east by a double bank and ditch (inner bank 6.5m above the ditch bottom) with a controlled straight entrance. The residence half is carried by the securely-identified motte-and-bailey form (motte tower plus bailey), the report's "military stronghold"; occupants are not named. |

Notes
Upgraded to assessed against Cadw full report CD092 (sig-20260722-report-cd092). The report securely classifies the monument as a motte-and-bailey and describes its defensive earthworks (motte, double bank and ditch, steep slopes), supporting fortified_residence: yes — the residence half is carried by the securely-identified motte-and-bailey form rather than by named occupants, which the report does not give. Other bands OMITTED: the report describes only earthworks and does not speak to them; as an obscure earthwork in woodland, popular_castle is left unassessed per the usage rule. Confidence medium.
