What does strongroom mean?
A strongroom is a specially built room designed to protect valuable or sensitive property. Its security may come from reinforced construction, heavy doors, restricted access, alarms, surveillance, and procedures governing entry. The term is especially common in banking, business, government, and archival settings, where it refers to a room containing cash, securities, valuables, or important records. In ordinary conversation, “strongroom” often has a formal, slightly old-fashioned sound and suggests not merely a lockable room but a place with exceptional security arrangements. It is occasionally used figuratively for a source of substantial financial resources, though its principal modern meaning is literal. The word is also commonly written as “strong room” in some varieties of English, but the one-word form is the standard dictionary spelling.
nounA specially constructed and heavily secured room used to protect valuables, documents, or other important property. It typically has reinforced walls and doors, controlled access, and additional security measures.
- A secure room or chamber designed to protect valuables, money, documents, or other property from theft, fire, or unauthorized access.

"The archive's most sensitive records were transferred to a secure strongroom before the renovation began."
The plural is formed by adding -s and is normal in both British and American English.

When security becomes architecture, the result is a strongroom: a room built to keep everything in and everyone else out.
