Arena Crenelated Wall

Description
"'Under the walls the mailed figures swarmed, battering at the gates, rearing up scaling-ladders, pushing storming-towers, thronged with spearmen, against the turrets.'"

- The Scarlet Citadel

The strength of walls during a siege is determined by two things - the strength of building itself and the ability of defenders to cleanly shoot enemies that are attacking.

These crenelated walls are a common design, effective at giving archers a clear space for firing on enemies as well as providing a niche for placing siege cauldrons and other defensive mechanisms.
