Mapparium(1935) Mary Baker Eddy Library in Boston, Massachusetts.


“The Mapparium is a three-story tall glass globe of stained glass that is viewed from a 30-foot-long (9.1 m) bridge through its interior. It is a unique exhibit at The Mary Baker Eddy Library in Boston, Massachusetts.

Built in 1935 and based upon Rand McNally political maps published the previous year, the Mapparium shows the political world as it was at that time, including such long-disused labels as Italian East Africa and Siam, as well as more-recently defunct political entities such as the Soviet Union. In 1939, 1958, and 1966 the Church considered updating the map, but rejected it on the basis of cost and the special interest it holds as an historical artifact.

Inspired by the famous spinning globe in the lobby of the New York Daily News building, they commissioned architect Chester Lindsay Churchill to design the Mapparium. Like its New York inspiration, the Mapparium features a panel of weather instruments.20120921-102118The 608 stained glass panels were produced by the Rambusch Company of New York and the Mapparium was opened to the public on June 1, 1935″.

  1. My husband and I have recently visited the Mapparium at the Christian Science Library in Boston. A few days after the visit, I actually realized why my husband wasn’t so impresed with his visit : he was sure there were microphones and speakers inside the sphere to amplify the voices of visitors. He thought that the particular acoustic of the place was actually due to an artificial voice amplifying system. I assured him that the acoustic within the Mapparium is all natural and due to the shape (shperic) and the material (stain glass) of the place but he won’t beleive me. I know there are speakers for the presentation (visual and sound effect) but what about for the visitor’s voice ? I looked everywhere on the internet and I even found result of a research about the acoustic of the place but nowhere is it written that the “whispering gallery effect” one can experience within the Mapparium isn’t helped by any microphones/speakers device. Can you help me convince my husband ?!
