THE ORIGIN OF MODERN FREEMASONRY
The origins of freemasonry are a topic of debate among Masonic Scholars. Most believe that the "speculative masonry" of today is a descendant of the guilds of early StoneMasons, or "Operative Masons" that built the early great structures of society. Modern Freemasonry traces its roots to June 24, 1717 when four Lodges in London, England met at the Goose & Gridiron Tavern to form the first Grand Lodge in the World.
