The Scottish Rite Masonic Museum & Library occupies a hilltop campus at 33 Marrett Road in Lexington, where Marrett Road meets Massachusetts Avenue about a mile east of the Battle Green. Founded in 1975 by the Scottish Rite, Northern Masonic Jurisdiction, as the National Heritage Museum, it pairs American history with one of the country’s deepest collections of fraternal and Masonic material. Admission is free.
Inside, the long-running exhibition “Sowing the Seeds of Liberty” covers the April 19, 1775, fighting through muskets, maps, and the stories of local families. Other galleries rotate through decorative arts, folk art, and fraternal history. The collection includes painted Masonic aprons, lodge furniture, regalia from groups such as the Odd Fellows, and everyday objects stamped with the square and compass. Researchers can book time in the Van Gorden-Williams Library & Archives, which holds books, manuscripts, and records on Freemasonry and American fraternalism.

The museum typically opens Wednesday through Saturday, 10 a.m. to 4 p.m. Confirm hours on its website before you go, because closures and special events can change the schedule. Weekday mornings are the quietest time to visit. Spring brings more crowds, when Patriots’ Day draws visitors to Lexington. The town’s America250 programming may also add traffic in 2026. Parking on site is free. Munroe Tavern sits just down Massachusetts Avenue, so you can easily walk to it. MBTA buses 62 and 76 run from Alewife to Lexington Center. Library research requires an appointment.
