However, Castell Coch, Tretower Court and Castle, and Plas Mawr are licenced for civil ceremonies, sites may be hired for a wedding blessing or for photographs.
Fodd bynnag, mae gan Castell Coch, Llys a Chastell Tre-tŵr a Phlas Mawr drwyddedau ar gyfer seremonïau sifil a gellir llogi’r safleoedd ar gyfer bendithio priodasau ac ar gyfer ffotograffau.
