I'm sure people probably recall the scene I'm talking about, but here's a recap:
At the conclusion of Raiders of the Lost Ark, Indy is assured that the Ark of the Covenant is in a "safe place" where, according to a guy who seems to be some government lackey, "our top men are working on it". Scene cuts to shots of the Ark being placed in a wooden crate, stencilled with "Top Secret Army Intel #9906753, Do Not Open!" and then wheeled away into the depths of a very large and mysterious/ominous-looking warehouse full of similarly marked crates.

Of course, we later discover in Crystal Skull that this warehouse is part of a (fictionalised) US Army base located in Area 51.
I am wondering whether this warehouse, which basically appears to be a US government equivalent of the "Department of Mysteries" in Harry Potter, was based on any particular real-life location or facility serving the same, or a similar, purpose?
Obviously I'm not talking about the US army base in Area 51, or the physical architecture of the actual warehouse building, but rather a place where the government stores items that it wants to keep hidden and secure from the rest of the world.
Also, I am sure that organisations like the CIA and NSA must have some locations that serve such a purpose, but I am after a specific example that is cited by the writers/producers/Spielberg and Lucas etc. in real life, not just easily inferred generalisations or speculation (I would welcome that kind of commentary in the comments, but NOT posted as answers).
