I'll be on travel to Boston and could like to visit, is there minimum requirements clothing to be able to visit. I'll will be decently clothes but might have only some trainers to wear. Will it be ok?

Feel free to tour the Grand Lodge building anytime from 10 a.m. to 2 p.m. Monday through Saturday. We welcome you as you are. To attend a lodge meeting you will need to be properly dressed. It would be best to contact the lodge you wish to visit directly. One of the lodges in the building requires tuxedo for everyone, including guests.

One should wear long pants and shirt or t-shirt. it is not recommended to wear shorts

I took my Nephew and the Masons were so nice to us! You might want to join a lodge after the experience. 👍
