Overlooking the Boston Common is the majestic Boston Masonic Building, home to the 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.
Public Hours and Tours
The building and library are open to the public! The administrative offices of the Grand Lodge are open from 8:30am to 4:30pm Monday through Friday.
Tours of the building are available on Monday through Friday between 10:30 a.m. and 2:00 p.m. If these days and times do not accommodate your schedule, please let us know and we will try to find an alternative solution. We are closed for tours on all state and federal holidays.
Our entrance is located at 51 Boylston Street; look for the glass doors adorned with golden square and compasses handles and you’ll know you’re in the right place!
We strongly encourage groups to plan tours during our scheduled hours, but if you would like to inquire about a tour at an alternative time, give us a call at (617) 426-6040 and we will work with you to find a time to accommodate you.
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.
