Federal brief
The codebreaking agency keeps a public museum on Colony Seven Road
NSA’s National Cryptologic Museum sits beside headquarters at Fort Meade, draws about 70,000 visitors a year, and posts its own hours. This brief does not freeze a Saturday rule the agency’s pages do not print the same way.
The National Security Agency publishes a museum. The about page puts it adjacent to NSA Headquarters at Fort George G. Meade, Maryland, at 8290 Colony Seven Road, Annapolis Junction, MD 20701, and it marks that street address as not a mailing address. The same page says the building holds thousands of artifacts and that, as one of the first public museums in the Intelligence Community, it hosts about 70,000 visitors a year.
Hours are where a register should stay fussy. The about page and the contact page agree that the museum is closed Sundays, Mondays, and federal holidays. They do not describe Saturday in the same parenthetical. This brief will not pick a Saturday rule for them. The phone on both pages is 301-688-5849, and the mailbox is crypto_museum@nsa.gov. Read the hours on nsa.gov the week you go.
The contrast with the Truman memorandum is the point of putting the two briefs next to each other. One file is a declassified carbon that created a communications-intelligence agency. The other is a street address the same agency expects strangers to use. Neither page is a tour of a current operation, and this register will not pretend it was let inside.
Publisher desk. The museum is NSA’s. This page is not. Not Legal Publication. Notice Nearby is not a newspaper.
