Boston Masonic Building

—— Located in the heart of Boston Common ——

Boston Masonic Building

Overlooking the Boston Common is the majestic, Grand Lodge of Masons in Massachusetts. One of oldest institutions in downtown Boston, the current building at 186 Tremont Street is the third Grand Lodge structure erected on the site. Built in 1898, it houses many treasures of great historical significance. It has six meeting halls, a research library dedicated to Freemasonry, and the administrative offices for the Grand Lodge and other Masonic bodies and programs.

Buildings Like This Aren’t Made Anymore
When you visit the current building, you’ll see why we say that no words can do it justice. Suffice it to say that buildings like this one — with its precise attention to detail, ornate fixtures, and expert craftsmanship — just aren’t made any more.

Inside the Building
Once you walk inside the building, you’ll be in awe of the high ceilings and the aesthetically pleasing design of our foyer. An image of our Grand Lodge seal greets you as the center piece of the mosaic tile design pattern that repeats throughout the building. If you are here for a tour, our security staff will direct you to the second floor lobby area, where you will wait to be greeted by your tour guide for the day.
