Dolbadarn Castle
Dolbadarn Castle is one of the most significant surviving native Welsh stone castles, built by Llywelyn ap Iorwerth (Llywelyn the Great) in the early thirteenth century. It stands on a rocky knoll overlooking Llyn Padarn at the foot of the Llanberis Pass, a critical route linking the heart of Gwynedd with the Conwy and Caernarfon regions. Its location demonstrates both strategic foresight and symbolic assertion of princely authority. The castle’s most striking feature is its massive round tower, standing about 15 metres high, widely regarded as the finest surviving Welsh round keep. Its thick masonry, narrow loops, internal stair and commanding position make it a masterpiece of native military architecture. The round keep embodies the Welsh princely tradition of strong, compact towers built for authority, defence and prestige. Dolbadarn also included a curtain wall that enclosed a small inner courtyard. Within this enclosure once stood domestic buildings such as a hall, chambers and service structures. These survive today only as low walls and rubble foundations. The layout reflects the compact, self contained nature of Welsh stone castles, contrasting with the sprawling concentric design of the later Edwardian fortresses. Although much of the castle is now ruinous, the round tower remains remarkably intact, giving a vivid impression of the site’s original power and presence. Dolbadarn was built to secure Llywelyn the Great’s control over Snowdonia, the heartland of the kingdom of Gwynedd. The castle guarded the crucial mountain pass and asserted Welsh dominance over a landscape that later became central to conflict with the English crown. One of the most notable events associated with Dolbadarn is the imprisonment of Owain Goch, brother of Llywelyn ap Gruffudd, who was held in the round tower for more than twenty years during the internal struggles for control of Gwynedd. In 1284, following the English conquest, Edward I seized the castle. He removed timber from its structures to aid in building Caernarfon Castle, indicating Dolbadarn’s decline in strategic importance. Unlike many Welsh strongholds, the castle was not rebuilt or significantly modified by the English, leading to its abandonment in the fourteenth century. By the eighteenth century Dolbadarn had become a celebrated subject of Romantic art, most famously painted by J. M. W. Turner, who was drawn to its dramatic setting and weathered silhouette against the mountains. The castle was placed in state care in 1941 and is now maintained by Cadw as one of Wales’s most important native-built fortifications.
