The Mapparium can be experienced only with a guide. As you traverse the 30-foot (9.1-meter) glass bridge that cuts through the interior of the globe, the view is enhanced by an original audiovisual presentation that uses words, music, and LED lights to illustrate how ideas can change the world. The Mapparium also has acoustics that turn the room into a whispering gallery. Letters and other artifacts document the construction and significance of the Mapparium.
Go on your own, or as part of a tour of Christian Science Plaza and other Christian Science buildings in the city. Access to the Mapparium is included in some Boston sightseeing passes.
