Dolwyddelan Castle

One of Llewellyn the Great’s fortresses built along the mountain passes to hold security of the region. Llewellyn ap Gruffyd held this castle against the invading English forces of Edward I. It stands atop a raised knoll with a commanding view of the vale of Conwy.

Dolwyddelan is unusual within Wales. In a land of castles, Dolwyddelan stands apart not as a stronghold erected by Norman or English forces but as a fortress of the native Welsh princes.

The first floor of the keepThe castle occupies a magnificent location deep in Snowdonia, on a ridge set against the rugged backcloth of Moel Siabod. It was built between about 1210 and 1240 by Wales’s most powerful medieval prince, Llwelyn the Great, ruler of Snowdonia.

Llwelyn’s stark and functional square tower, which can be seen for miles around, controlled a strategic pass through his mountainous kingdom from Merionethshire to the Vale of Conwy.

The core of the castle, the rectangular stone keep, was supplemented later in the 13th century by a stone curtain wall enclosing the courtyard. If the battlements and wall walks look a little too perfect for such a weather beaten spot, it is because they were restored in Victorian times.

Dolwyddelan CastleDolwyddelan, a key mountain stronghold, saw active service in the late 13th century wars between the Welsh and Edward I. It fell to English forces in 1283 and was refortified, probably with a second rectangular tower which today stands in ruin.

A visit to this solitary sentinel is worth it for the views alone – the sweeping mountain vistas visible from its battlements are truly stunning.
