Nearly 20 years after America was born, an Irish architect named James Hoban began laying down the first piece of stone for what would become the White House during an elaborate Freemason ceremony.
Less than 24 hours later, the first piece of stone that was laid down vanished and no one appeared to know its whereabouts. Since then, the search for the stone continues as various participants have attempted to locate the historic piece of foundation.
Although the formation of the Freemason's fraternity is a fiercely guarded secret, their history dates back to 1390 when they were first referenced in a Regius Poem.
A commonly accepted theory is the group emerged from the stonemasons guild amid the middle ages.
In the late 1940s during President Harry Truman's administration, the White House underwent major renovations as crew members brought in metal detectors in hopes to locate the stone by picking up its metallic minerals and many believed they may have discovered its location.
When Truman got wind of the search, he ordered them to halt the exploration immediately, which caught everyone off guard. In response, Truman then sent pieces of the White House to several various Freemason locations throughout the country.
