Claim: In the construction of the Harlech Castle in 1282 in North Wales, the carpenters and stonemasons were orderd by King Edward I, who is also known as Edward Longshanks and the Hammer of the Scots, started in June and by winter of 1283, the first 15 feet of the inner walls were completed.
Evidence: 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. Edward ordered the construction of a castle at Harlech, one of seven built across North Wales in the wake of the 1282 campaign. Money to pay for the initial phase arrived in mid-May and carpenters and 35 stonemasons were dispatched in June and July to commence work. By the winter of 1283, the first 15 feet (4.6 m) of the inner walls had been constructed, allowing the castle to be defended in the event of an attack, and a small, planned town had been founded alongside the castle. Edward I (17/18 June 1239 – 7 July 1307), also known as Edward Longshanks and the Hammer of the Scots (Latin: Malleus Scotorum), was King of England from 1272 to 1307.
