#Harlech #Castle #Wales In local mythology, the site of Harlech Castle in North Wales is associated with the legend of Branwen, a Welsh princess, but there is no evidence for a native Welsh fortification having been built there.[4] The kings of England and the Welsh princes had vied for control of North Wales since the 1070s and the conflict was renewed during the 13th century, leading to Edward I intervening in North Wales for the second time during his reign in 1282.[5] Edward invaded with a huge army, pushing north from Carmarthen and westwards from Montgomery and Chester.[6] English forces advanced down the Conwy valley and through Dolwyddelan and Castell y Bere, onto Harlech, which Sir Otton de Grandson took with 560 infantry in May.[
