“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.The 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″.
