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 Cadw's report describes a curtain wall, cross arrowslits, a turret with an arrowslit and a full-height garderobe tower alongside a residential south block containing a first-floor hall and solar — combined active defence and lordly residence, held by the de Braose lords.
Enclosure fortification unassessed No source consulted so far speaks to this definition. Unassessed is not the same as no.
State fortification unassessed No source consulted so far speaks to this definition. Unassessed is not the same as no.
Palatial seat unassessed No source consulted so far speaks to this definition. Unassessed is not the same as no.
Revival and folly no A late-13th to early-14th-century castle of the medieval era held by the de Braose lords; later reuse as an 18th-century debtors' prison is adaptation of the real castle, not a purpose-built sham or revival.
Popularly a castle unassessed No source consulted so far speaks to this definition. Unassessed is not the same as no.

Notes

Assessed from Cadw's full designation report (GM012), the visible "New Castle". fortified_residence: yes — arrowslits, garderobe tower and curtain wall are active defence, integrated with a residential hall/solar block held by lords. revival_folly: no — a medieval castle, later adapted (debtors' prison), not a folly. palatial_seat OMITTED (borderline, deliberately not asserted): the report notes the New Castle was built when "Edward I's pacification of Wales had deprived it of any military importance" and describes a "picturesque arcaded parapet" on the residential block — suggestive of decorative fortification — but the same block retains functional arrowslits and a garderobe tower, and the towers were sold off for economic rather than amenity reasons, so the report does not clearly evidence an unfortified palatial phase; left unassessed rather than inflated. popular_castle OMITTED: no visitor/usage evidence in the report. Confidence medium: single official report plus register.
