One of the world's largest gold depositories was stored underneath the World Trade Centre, owned by a group of commercial banks. The 1993 bomb detonated close by the vault held. Seven weeks after the September 11 attacks, $230 million in precious metals was removed from basement vaults of 4 WTC, which included 3,800 100-Troy-ounce registered gold bars and 30,000 1,000-ounce silver bars.
The rubble just landed in the basement's empty void where all that gold was supposed to be.
