Mae gwelliannau eraill i’r Castell yn cynnwys gosod grisiau troellog dur gwrthstaen yn y tŵr gogledd-ddwyreiniol a chynllun i ystyried adfywio Blaendraeth Fflint ymhellach.
Further improvements to the castle include the installation of a stainless-steel spiral staircase within the north-east tower and a masterplan to consider the wider regeneration of the Flint Foreshore.
