Yn ystod fy ymweliad, clywais mai'r rheswm dros hyn oedd bod ystod eang o staff wedi dod i'r ysbyty ddydd Sul ac ar ŵyl y banc ar y dydd Llun yn ystod eu diwrnodau i ffwrdd.
The main hospital ward, which was full of patients at the time, remained in operation throughout due to quick thinking staff who prevented flood water from entering the ward.
