Any city or town is nothing without strong and reliable defenses. When your city is undefended, raiding enemies may storm to your town anytime and take all the resources you’ve worked so hard to gather.
The game offers players several defensive buildings you may put together in order to keep your town, and most especially your resources, safe.
Just like all other buildings in the game, the benefits it provides is further enhanced through building upgrades. Upgrading Defensive buildings usually costs Gold.
Most of the defensive buildings are available upon reaching the Iron Age but there will be some that may only be available upon reaching a more advanced stage -- like the Enlightenment Stage.
