Edward Is successful 13th-century campaign in the region was cemented by the creation of an English borough in Denbigh from 1282 onwards. He simply built on top of what was a traditional Welsh stronghold. In so doing he made sure all traces of Dafydd ap Gruffudd, the previous unlucky incumbent, were removed for ever
Henry de Lacy, one of the Kings loyal commanders, was given control of the area and had the task of building the new castle. He couldnt go far wrong with the kings master mason, James of St George, at his side.
It wasnt all plain sailing however.
A Welsh rebellion, led by Madog ap Llywelyn, captured the partly-built castle in 1294 but soon enough Edwards dominance and the castle building programme were restored. You can see for yourself the two phases of building work. The post-rebellion work is marked by different colour stone, thicker curtain walls and a hint of Caernarfon-style angular towers.
