Siege Workshop (Age of Empires III)

Siege Workshop has been replaced by Artillery Foundry since the Siege Units are now known as Artillery Units. However, the Iroquois use a Siege Workshop, which is a unique building among Native American Civilizations, being the only one among them with Artillery units. It is available at Fortress Age.
