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 | Cadw report GM358 records a castle or fortified house on an artificially levelled rectangular platform defended on west and south by steep natural slopes and across the north and part of the east by a constructed ditch, with a rectangular residential building (14m by 12m) and an abutting courtyard. Defence and a lordly residence coincide on one site, satisfying both halves. |

Notes
Assessed 2026-07-22 against Cadw scheduled-monument full report GM358 (sig-20260722-report-gm358); fortified_residence upgraded to assessed. Defence here is modest (turf-covered walls, ditch, natural slopes) but coincides with a clear residential building, and the register frames it as "castle or fortified house". enclosure_fortification NOT assessed — an identified lordly residence excludes it from that band. popular, palatial, revival and state bands OMITTED, unspoken to by the report. Confidence medium: single official report plus register.
