Aberdyfi Castle, Medieval motte castle in Ysgubor-y-coed, Wales.
Aberdyfi Castle is a medieval motte castle consisting of a tree-covered earthen mound approximately 20 feet (6 meters) high with a roughly 30-foot (9 meters) diameter at its summit. The mound sits on a low ridge positioned between two rivers, surrounded by wetland terrain.
The fortress was built in 1156 by Lord Rhys as a defensive structure against potential threats to the region. It fell briefly under Norman control in 1158 before being returned to Welsh hands.
This fortress served as a gathering place where Welsh leaders met to negotiate alliances and territories among themselves. Such assemblies demonstrated the site's importance in the political landscape of medieval Wales.
The site is best reached on foot but visitors should be prepared for soft and wet ground throughout the surrounding area. Appropriate footwear is essential as the terrain becomes particularly muddy after rainfall.
The mound bears the Welsh name Domen Las, meaning blue mound, reflecting a local connection to the landscape that may relate to its original appearance or distinctive features. This native name persists in regional records and local knowledge.
