Castell Dinas Bran

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.

DefinitionVerdictBasis
Fortified residence yes A stone castle built in the 1260s by the lords of Powys Fadog occupies the hillfort's north-west corner; a rock-cut ditch, a keep well preserved on its south and west, an intermittent curtain wall and a typically Welsh apsidal tower give active defence, and the great hall or chapel with surviving arched windows housed the lord.
Enclosure fortification yes A later prehistoric (probably Iron Age) univallate hillfort crowns the steep isolated summit, its rampart enclosing an undulating interior with visible possible hut sites and a probable south-west entrance — a defended enclosure with no identified lordly residence.

Notes

Bands assessed against Cadw's full scheduled-monument report (DE021), which describes two phases. enclosure_fortification: yes for the Iron Age univallate hillfort on the summit; fortified_residence: yes for the 1260s stone castle of the lords of Powys Fadog built into the hillfort's north-west corner. Both hold at once — this is not an inconsistency but the two-phase site the report documents. Other bands omitted; the report does not speak to popular usage, palatial conversion, or folly. One official report, so confidence is medium.
