Ewloe Castle

Ewloe Castle is a rare example of native Welsh military architecture from the 13th century, built by the princes of Gwynedd in resistance against Norman and English expansion. The castle's distinctive D-shaped stone tower was likely constructed by Llywelyn the Great after 1210, with curtain walls and a circular western tower added by Llywelyn the Last decades later. Unlike many Welsh fortifications, Ewloe reflects its strategic purpose through irregular design rather than display, sitting in a secluded wooded valley near Deeside in Flintshire. The castle was abandoned in 1277 when Edward I rendered it obsolete with the construction of nearby Flint Castle, leaving it to fall into romantic ruins now protected by Cadw with free public access.
