—Age of Empires II description
The Siege Workshop is a military building in Age of Empires II that becomes available once the Castle Age is reached and a Blacksmith is built. It trains and upgrades siege weapons.
Tactics and placement 
Edit
The Siege Workshop is an essential building for all players as land siege engines (with the exception of Trebuchet and Petard) are created here. Siege Workshop units can rarely act on their own and need protection from other units, so it is advisable to train other units first.
The work rate of the Siege Workshop is slow and cannot be improved, so any player who want to create Siege Workshop units in any relevant numbers should have at least four of them. It is advisable to build Siege Workshops near an enemy's settlement if playing offensively as this will cut off distance, especially considering all siege weapons move really slowly.

History Edit
"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."
