Arsenal

ar·se·nal (är′sə-nəl)

A government establishment where firearms and ammunition are stored, repaired, or manufactured. The term is misused by the media to mean more than one firearm or any quantity of ammunition, as in "they found an arsenal."A governmental establishment for the storing, development, manufacturing, testing, or repairing of arms, ammunition, and other war materiel.

   

Over the centuries an Arsenal has included every variant of such a place, whether privately or publicly owned (with the latter in older royal and modern state-owned versions).
