Castell Llansteffan
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 | A square gatehouse defended by portcullis and doors, a later double-towered gatehouse (modelled on Caerphilly's East Gate) with front and rear portcullises, five murder holes and outer machicolations, wall-walks carried on vaults and D-shaped mural towers provide active defence; the North Tower and the gatehouse's well-appointed great rooms with fireplaces served as the lord's private accommodation — both halves met. |
| Enclosure fortification | yes | The promontory neck was first defended in the 6th century BC when a double bank and ditch were thrown across it to form a promontory fort — a prehistoric defensive enclosure with no identified lordly residence — satisfying this band for that earliest phase. |
| State fortification | unassessed | No source consulted so far speaks to this definition. Unassessed is not the same as no. |

| Revival and folly | unassessed | No source consulted so far speaks to this definition. Unassessed is not the same as no. |

Notes
Upgraded to an assessed record from Cadw's full report (CM004). Two bands carry verdicts for two phases: enclosure_fortification 'yes' for the Iron Age promontory fort, fortified_residence 'yes' for the medieval castle. The Tudor conversion 'from a military structure into a comfortable residence' was weighed for palatial_seat but left unassessed — the castle retained heavy defences and the change was a blocked gatehouse, not a palatial rebuild. popular_castle left unassessed (taken into state care in 1959, but the report gives no visitor-operation or tourism evidence).
