Dolbadarn Castle, a fortification built by the Welsh prince Llywelyn the Great during the early 13th century, is located at the base of the Llanberis Pass. The castle was important militarily and as a symbol of Llywelyn's power and authority. It features a large stone keep, which historian Richard Avent considers "the finest surviving example of a Welsh round tower".[17] In 1284 Dolbadarn was taken by Edward I of England, who removed some of its timbers to build his new castle at Caernarfon. Dolbadarn was used as a manor house for some years, before falling into ruin. In the 18th and 19th century it was a popular destination for painters interested in Sublime and Picturesque landscapes. It is now owned by Cadw and managed as a tourist attraction, and is protected as a grade I listed building.
