Caernarfon Town Walls is a medieval defensive structure enclosing the historic town of Caernarfon in Conwy, Wales. The walls were constructed in the late thirteenth century following Edward I's conquest of North Wales, forming part of the strategic fortification programme that secured English control over the region. The circuit comprises substantial stone masonry with rectangular towers at intervals, reflecting contemporary military engineering practices designed to defend both the town and its castle. The walls remain substantially extant and represent a significant example of late medieval urban fortification in Wales, demonstrating the integration of town defence with the broader castle and garrison network established during the Edwardian conquest.
