Beaumaris Town Wall is a medieval defensive structure enclosing the planned town of Beaumaris on the Isle of Anglesey, Wales. Constructed in the late thirteenth and early fourteenth centuries following the English conquest of Wales, the wall formed part of Edward I's strategic fortification programme in North Wales and protected the newly established town adjacent to Beaumaris Castle. The wall survives in fragmentary form, with sections of ashlar masonry still visible in places, demonstrating the substantial stone construction typical of major Welsh town defences of this period. It represents a significant example of medieval urban planning and military architecture, reflecting the integration of castle, town, and defensive perimeter in establishing English administrative control over conquered Welsh territories.
