Freemasonry began in medieval Europe as a guild for stonemasons who built the great castles and cathedrals of the Middle Ages. Today it is one of the largest fraternal and charitable organizations in the world. The United Grand Lodge of England at Great Queen Street in London, over 300 years old, boasts The Library and Museum of Freemasonry. Open to the public, it’s located on the first floor of Freemasons’ Hall, where guided tours of the Grand Temple and ceremonial areas are provided when the hall is not in use. The free museum displays one of the world’s largest collections associated with Freemasonry, including pottery and porcelain, glassware, silver, furniture, clocks, jewels, regalia and items belonging to famous Freemasons like Winston Churchill and King George IV (the first Royal Grand Master). The closest tube stations are Holborn, Covent Garden and Leicester Square.
