An armory is a place where weapons and military equipment are stored and maintained. In medieval castles, the armory might hold swords, shields, spears, and suits of armor, all carefully organized and kept ready for battle. A modern military armory contains rifles, ammunition, and other gear that soldiers need.

Think of it as a specialized warehouse for military supplies: everything is cataloged, secured, and regularly inspected to make sure it works properly when needed.

Many cities have historic armory buildings that once served state militias or National Guard units. These imposing structures, often built like fortresses with thick walls and heavy doors, now sometimes host community events, sports competitions, or serve as museums. The term can also refer to a weapons factory where military equipment is made.

You might also hear armory used figuratively to mean a collection of tools or skills someone has available. A debater might have an armory of arguments ready to use, or a musician might have an armory of techniques they've practiced. In this sense, it means having resources ready and organized for when you need them.
