The Siege Workshop in this version of the game have the same purpose as its precursor. The Siege Workshop specializes in building and upgrading siege weapons, which are designed to take down enemy infrastructure during a siege.
The construction of castles and fortified towns created demand for artillery engines that could knock down walls and open the fortification to assault by troops. Without such artillery weapons, the taking of a castle required a long and costly siege that eventually starved the defenders into surrender. The ability to lay siege was constrained by the length of the campaigning season, the cost of providing supplies to a besieging army, the losses from disease in camp, and weather. Battering rams, trebuchets, and other siege engines were used to break into the fortification quickly and decide the issue. Siege engines were built at a siege workshop.
