The Cannon Control Building is a limited time building released during the Christmas 2014 Event on December 24, 2014. It was the second prize to be unlocked in the Winter 2014 Part 2 prize track. It's main function during the Event was to manage the upgrades to the Elf Cannon. Those upgrades are achieved by spending Cogwheels. It functions similarly to the Castles during the Clash of Clones 2014 Event.
