Near this spot at his manor of Glyndyfrdwy, Owain Glyn Dwr proclaimed himself Prince of Wales on 16th Sept 1400, so beginning his 14 yr rebellion against English rule. This mount, known locally at Owain Glyndwr’s Mount, is actually the remains of a 12th century castle motte built to command the route through the Dee Valley. Like the motte nearby at Sycharth, it may have continued in use until the late 14th Century but Owain’s manor is likely to have been in the square moated area across the field. This would have been defended by a water filled moat, pallisade and gate.
