The Keep

The Keep is the only building that is automatically placed in every new castle you unlock (in kingdoms) or an outpost you capture. "The Keep" controls the basic "Construction speed" for every building in the castle or outpost (this can be further enhanced by doing proper research) and also the amount of "safe storage" which means the amount of each resource that can not be looted on attacks (up to 2,000 on level 6). When defending, the courtyard battle takes place at "The Keep". The design of the keep changes with every level and it is also reflected on the map.
