CONWY Castle (aka Conway Castle), located in North Wales, was built by Edward I of England (r. 1272-1307 CE) from 1283 to 1292 CE to protect and maintain, along with several other castles, his newly acquired dominance in the region. Built on a rock promontory, the castle incorporated the latest defensive design features such as massive round towers, a double courtyard or bailey, and outer barbican defensive walls and towers. Conwy Castle is listed by UNESCO as a World Heritage Site.
From 1272 CE Edward I, the new king of England, conquered most of Wales and joined it with the county system present in England. Following the death of Llywelyn, the Prince of Wales, in 1282 CE, the only part of Wales which remained free was the wild mountainous north and here the king built several major castles which included Caernarfon Castle, Harlech Castle, and Conwy Castle. Work began on Conwy Castle in March 1283 CE and would continue over that decade, the vast team of labourers, masons, and craftsmen being supervised by Master James of Saint Georges (c. 1235-1308 CE), the experienced architect and engineer who had previously built castles in Europe and who would be involved in many of Edward’s other Welsh castles.
