What is recorded here

Dolwyddelan Castle is a thirteenth-century stronghold built by Llywelyn ab Iorwerth to guard a vital valley route, standing as a circular enclosure of local grit and slate. It outlasted Edward I’s capture and later private repairs to become a graded monument, yet its walls still mark the moment a Welsh prince stopped relying on the older Tomen Castell tower. The castle remains partly ruinous but open to visitors, preserving the defensive purpose that shaped this corner of Conwy.

The National Monuments Record of Wales records Dolwyddelan Castle as Castle from the Medieval period. The saved point comes from the official national record. Inclusion does not by itself mean that the public may enter the place.

Dolwyddelan Castle was built by Llywelyn the Great, Prince of Gwynedd, in the early 13th century. It is important as a well-preserved example of a Welsh mountain castle and symbolizes Welsh resistance to English expansion during the Medieval period.
