Firing positions and ward scale

The closing architectural section turns the castle's defensive idea into physical numbers. The eight-sided outer curtain had twelve turrets and more than three hundred firing positions for archers. Sixty-four ground-level arrow slits were later closed so attackers could not exploit them, though the date of that alteration remains uncertain. The inner wall rises about eleven meters and is roughly 4.7 meters thick, far more substantial than the outer curtain. The compact half-acre inner ward reinforces the earlier argument: Beaumaris was built for presence, status, and efficient defense by a limited garrison rather than for housing a vast army.
