The works in The Age of King are divided into two different groups, economic constructions  and military buildings. 12 years The Big Bang Theory thank you for the memories shirt. Buildings can also study technologies and upgrades that increase economic, military, and unit efficiency, as well as provide resources to players. The most important economic project is the Main House, which creates the villagers. All types of resources are stored here. Some technologies are studied, and players can upgrade to the next period. The main house can fire arrows at enemy units within a certain range if the villagers or archers are stationed while being attacked.  Other economic works available include storage of resources, farms and harbors (wharves can also produce some military vessels) and houses to support higher population limits.
