A depository is a place where things are kept or stored. You might call your city's Natural History Museum a depository of local dinosaur fossils.

A library could also be called a book depository, since books are stored there, and the official name of Fort Knox, which once stored much of the gold in the US, is the United States Bullion Depository. The word depository literally means "place where things are deposited," from the Latin root deponere, "lay aside or deposit," combining de-, "away," and ponere, "to put."
