In 1283, the Great Hall of Caernarfon Castle in Wales was completed, serving as a symbol of Edward I's conquest of Wales. This monumental structure not only showcased the military might of the English crown but also represented the cultural and political dominance over the Welsh people. The castle's architecture influenced subsequent castle designs across Europe, reflecting the era's feudal power dynamics and the importance of strongholds in governance.

The construction of Caernarfon Castle and its imposing architecture inspired poets like Dafydd ap Gwilym, who wrote about the landscape and power struggles of Wales. The castle became a symbol in Welsh literature, representing both oppression and resilience, themes that resonate in many poetic works from the period.
