A fort is a extra defence for an empire. anyone attacking withing a 30 studs radius of the fort will have to attack it first before they attack the nearest settlement. Forts should be placed near settlements since they have the same cultural outreach of a colony or you might face annexion from a foreign empire. Forts should have a good level of defence, for example making a single route up a steep mountain and add the top having platforms where you can eventually place artillery units when in war. By doing so you can reduce the amount of deaths on your side and increase the deaths of your enemies. Note no fortress is impossible to take over.
