The Chronicles of Ewloe
Trace the story of Castle Ewloe from its strategic origins through the turbulent centuries of Welsh resistance to its modern preservation.
The Battle of Ewloe / Coleshill
Owain Gwynedd ambushed the forces of Henry II in the wooded borderland near Coleshill/Ewloe. The episode shows the military value of the difficult woodland landscape long before the later stone castle was built.
Llywelyn ab Iorwerth's Expansion
Llywelyn ab Iorwerth, known as Llywelyn the Great, expanded Welsh power in north-east Wales. Some modern interpretations suggest that the earliest stone phase at Ewloe, including the D-shaped tower, may date from after this period of expansion.
A Welsh Stronghold at Ewloe
Castle Ewloe is traditionally associated with Llywelyn ap Gruffudd and is often dated to around 1257. However, the castle may have developed in phases, with earlier work possibly linked to Llywelyn ab Iorwerth and later strengthening associated with Llywelyn ap Gruffudd.
Later Fortification
The castle's curtain walls, lower ward and western circular tower may belong to a later phase of Welsh fortification. These additions reflect the continuing importance of Ewloe in the contested borderland between Welsh rulers and English power.
Edward I's First Welsh War
Edward I's campaign against Llywelyn ap Gruffudd ended with the Treaty of Aberconwy. Ewloe came under English control without evidence of a major siege, and its importance declined as Edward's new castles reshaped military control in north Wales.
The Fall of Llywelyn ap Gruffudd
Llywelyn ap Gruffudd was killed during Edward I's second Welsh war. After the conquest of Gwynedd, Ewloe remained within English-controlled territory and gradually lost strategic importance.
