Housed inside The Mary Baker Eddy Library, the Mapparium is a one-of-a-kind experience. Visitors walk across a clear glass bridge to look out from the center of a three-story, stained glass globe. Created by architect Chester Lindsay Churchill in 1935, the Mapparium was renovated in 2002 for the opening of the Library with LED lighting, but retains the world map of the 1930s featuring USSR, colonized Africa, and more. 

The Mapparium is one of the Library's permanent exhibits and can be seen on a ticketed tour, Tuesday through Sunday, 10:20 AM to 4:00 PM.  Tours last 20 minutes; photography is not permitted in the Mapparium.
