Defensive Wards

A city improvement obtained from the Citizen Armies technology in Research Era II. Can only be built once in your empire, and cannot be rebuilt if destroyed. It should also be noted that, unlike other City Improvements that have a "per " effect, the city this improvement is constructed in will gain +30 per  no matter how they are assigned.

Lore
By dividing the city into a series of wards, with the citizens of each ward responsible for the upkeep and patrolling of the walls, city defense is greatly improved.
