Ewloe Castle was built by native Welsh prince Llywelyn ap Gruffudd after he captured the lands forming most of modern-day Flintshire from the English Crown in 1257. It is thought that the castle may have built upon earlier fortification work by his grandfather, Llywelyn the Great, and great-grandfather, Owain Gwynedd.
The castle’s life was short and it was abandoned after the conquest by Edward I of England in 1277 and fell into ruin.
The remains of Ewloe Castle are managed by Cadw, the Welsh Government body responsible for conserving and managing historically significant monuments and sites in Wales. It is open to the public with free admission.
