What to call an area where old items are stored

I have an area in an app where old items are stored, using a 'locked' metaphor. Items can be unlocked, and brought back, but after they're locked, they are sent to a larger list of locked items and hidden from the main view.

I need a one word title for an area where locked items are stored. Right now, its called 'Archives', and has a lock symbol above it, but this feels like a bit of a mixed metaphor

My alternative is to call old items 'Archived', but my issue there is 'Unarchive' feels like awkward phrasing.

What's a good way for this metaphor to really follow through?
