Ewloe Castle is situated in Wepre Park, near the town of Ewloe about a mile northwest of Hawarden and southwest of Connah's Quay.
Ewloe Castle rises northwest of the town of Hawarden, and is a relic of the brief triumph of the Welsh prince Llywelyn the Last, who began its construction in 1257 after his reconquest of this part of Wales. Of all the native castles in North Wales, Ewloe is the only one with an unspectacular setting. It stands on a promontory overlooking the junction of two streams, but is overwhelmed by higher ground at south. Its position near the English border was strategic, controlling the road to Chester. It stood within the forest of Ewloe, surrounded by woods and in a great position for hunting.
