CHICAGO (CBS) — For the first time ever the doors of the vault in the Chicago Board of Trade building have been swung open for the public to take a peek inside.

The vault has held many a valuable item in the 83 year history of the building, including gold, silver, and cash, but it’s empty now.

As part of the Chicago Architecture Foundation’s Open House Chicago program, the public can now take a tour.

Building manager Michael Giese says it will remain open for history and architecture buffs and tourists.

“Visitors that want to come through and see something related to the history of the building and now we have something to show them,” said Giese.
