A friend asked me where the largest (by volume) bank vault is. This is tough to answer because even if a vault is known to exist, the dimensions are seldom stated. For example the 1902 vault at 25 Broad Street in NYC (now Bobby Van's Steak House). Here's what I was able to come up with:

1 - Trinity Place, NYC. Two levels; one is 85x20x8 feet, the other is 108x31x8.5 for a total of 42,058 cubic feet.

2 - One King West, Toronto. Two levels though the size is simply stated to be 33x33x25 for a total of 27,225 cubic feet.

3 - Boston Stock Exchange. The vault is stated to be 66x40 (outside dimensions); assuming 8 feet high and ignoring wall thickness, 21,120 cubic feet.

4 - San Francisco, Diebold, Norris & Co., 1874. No doubt long gone, it was stated to be 27x32x12 for a total of 10,368 cubic feet.

5 - San Diego, Marriott Hotel. The vault is stated to be 27x39x8 for a total of 8,424 cubic feet.

What large vaults can you come up with?
