Grand Masonic Lodge of Massachusetts (The Freemasons)

The Grand Lodge of Massachusetts is the administrative headquarters of Freemasonry in the state, based in a historic Masonic building in downtown Boston that overlooks Boston Common. Beyond its own offices, the building serves as the meeting home for more than 20 Masonic organizations. It also houses the Samuel Crocker Lawrence Library, one of the largest and most important Masonic collections in the world.

Freemasonry describes itself as the world’s oldest and largest fraternity, made up of men 18 and older of good character from every country, religion, race, age, income, education and opinion. Its system of ethics rests on the idea that each member has a responsibility to improve himself while remaining devoted to his family, faith, country and fraternity. The Massachusetts Grand Lodge dates to 1733, making it one of the oldest Masonic grand lodges in the world.
