Carreg Carn March Arthur is a boundary stone, on which is a plaque which reads "The stone underneath this Arch Carreg Carn March Arthur was Adjudged to be the Boundary of the Parish and Lordship of Mold in the county of Flint and of Llanverres in the County of Denbigh by the High Court of Exchequer at Westminster 10th November 1763". Legend has it that the stone bears the hoofprint of King Arthur's horse as he leapt from a nearby cliff to escape the invading Saxons.
