Castell Dolbadarn is a medieval castle occupying a prominent hilltop position in the Llanberis Pass, within the modern county of Conwy in north Wales. Built in the early thirteenth century, likely during the reign of Llywelyn the Great, the castle served as a stronghold of the native Welsh princes and demonstrates the military architecture of the Gwynedd dynasty. The surviving structure comprises a substantial circular stone tower, known as a round keep, which dominates the site and reflects both Welsh and Norman-influenced defensive design. The castle was gradually abandoned following the English conquest of Wales under Edward I, with the tower remaining as a conspicuous landmark and testament to medieval Welsh princely power in Snowdonia.
