Judges said of Castell Dinas Bran: "This 13th-century ruined castle atop a rugged pinnacle offers commanding views of Welsh valleys and has long captured visitor’s imaginations.
"Sitting high above Llangollen and alongside Iron Age embankments, it is a place of romance and legend.
"Wordsworth wrote of it: 'Relics of kings, wreck of forgotten wars, To the winds abandoned and the prying stars.'"
Judge Phoebe Smith says: “It is home to a legendary giant and is steeped in wonderful Welsh folklore.”
