The Armory is a stone stronghold located on the eastern side of Alicante. It is used a storehouse, museum and research center, and contains a vast array of weaponry for Shadowhunters to choose from and use for conflicts within Idris. Only Clave members are allowed access to the weaponry; those who are not part of the Clave are restricted to the south wing of the Armory, which contains a variety of antiquated and legendary weapons.
The Armory is the only place where Iron Sisters can be found outside of the Adamant Citadel. They make use of the Armory's vast, labyrinthine basement levels to perform their research and make repairs and new weapons, for their protection.
The Armory was built in the early 1800s in a medieval style, resembling a fortress due to its high walls and turrets. While built to give the appearance of being able to withstand artillery fire, the building does not function as a fortress and cannot withstand such bombardment, hence the reason that the Iron Sisters perform their duties in the basement levels.
- A passage within the basement levels is believed to lead directly to the Adamant Citadel.
