What is recorded here

Dinas Emrys stands as a layered Welsh fortress where Roman, early medieval and later castle works share one steep hill above the Glaslyn valley. Its story mixes proven ambition with legendary warning: a rich leader may have drunk distant wine there, a Welsh prince may have raised a keep before 1240, and tradition claims Vortigern failed to build until Myrddin Emrys revealed two dragons fighting beneath the mountain. What remains is not a grand ruin but a sharp place to imagine: walls reduced to fragments, a buried tower base, a narrow rocky approach and a view that still commands the land.

The National Monuments Record of Wales records Dinas Emrys as Castle; Hillfort from the Medieval; Early Medieval; Roman; Iron Age period. The saved point comes from the official national record. Inclusion does not by itself mean that the public may enter the place.

Dinas Emrys was originally an Iron Age hillfort, later occupied and possibly modified by the Romans and then used again in the Early Medieval period. It is historically important as a site linked to Welsh legend, particularly the stories of Merlin and the Two Dragons.
