The Ground Zero Cross was discovered by construction worker Frank Silecchia.  He came across it in the rubble of the World Trade Center just a few days after September 11, 2001.  It stood straight, twenty-feet high, surrounded by a number of smaller crosses.  It was not simply cross beams that remained from an existing building.  It was formed out of beams from Building One that had plunged, split and crashed into Building Six!  The cross weighed a couple of tons.
