Castell Caergwrle is one of Cadw’s most recent acquisitions through Guardianship, although the wider site remains in the ownership of Hope Community Council.
Castell Caergwrle yw un o gaffaeliadau diweddaraf Cadw drwy Warcheidiaeth, er bod y safle ehangach yn parhau ym mherchnogaeth Cyngor Cymuned yr Hôb.
