Castlehunting #1

My firstborn Child, Mother of Castles, Lady Angharad Rhiannon Howell-Parry, has set me the task, in my otium, to hunt down & catalogue the interpretation features of all the Cadw monuments in Wales. As they all belong to her. 

Starting at home, I am radiating outwards, hence the first in this series is Oxwich Castle, or Castell Oxwich in Welsh.

It was closed. It seems that it usually is.
