The city wall provides a defence bonus to friendly units with the fortify skill in the city. The defence bonus provided by a city wall is significantly stronger than other defence bonuses (see Combat). Units in cities with walls have a double shield around their health. Cities with a wall have a wall visual on the bottom.

The city wall is one of the two rewards for upgrading a city to level 3, the other being resources (5 stars).

Trivia

  • Before the fortify skill was introduced, the city wall provided the defence bonus to all units except those unique to special tribes, including the Giant.
