Meanwhile, visitor research conducted by Cadw during summer 2018 identified 16–24 year-olds as the fastest growing demographic, accounting for 10% of visitors surveyed (vs. 7% in 2015).
Yn ôl gwaith ymchwil Cadw ar ei ymwelwyr yn ystod haf 2018, y grŵp o bobl rhwng 16 a 24 oed oedd y ddemograffeg sy’n tyfu gyflymaf.
