Dolbadarn Castle Ruins

The stately remains of Llywelyn the Great's mighty fortress. 

Already in ruins by the time it was captured in glowing colors by romantic painter J. M. W. Turner in 1802, Dolbadarn Castle dates back to the days of the legendary Welsh ruler Llywelyn the Great in the 13th century.

The 50-foot tower of Dolbadarn Castle watched over the Llanberis Mountain Pass. Once a strategic stronghold, it’s now mostly popular with rock climbers and outdoor adventurers who come to explore the craggy landscape.

In 1284 the castle was seized by Edward I during his invasion and conquest of Wales. Although the castle remained a manor house until into the 14th century, the slow decline of the fortress began when Edward removed some timber to add to the construction of his great castle at Caernarfon, his seat of power.
