@mattblaze@federate.social I walk past this regularly and had no idea… thanks.

The Motion Picture, Broadcasting and Recorded Sound Division of the Library of Congress now occupies what was once a cold war Federal Reserve facility for storing money in Culpeper, VA.
(for some reason you still need cash after everything else has been vaporized)

The buried concrete vaults are repurposed for storing nitrate film. (much better use IMHO)
