Visit the Mapparium
Most tourists wouldn’t visit a library while in Boston, but there is a good reason to visit the Mary Baker Eddy Library’s ‘Mapparium’. It’s a giant globe made up of 608 glass sections, reaching a height of three stories, 30-feet wide! Built in the 1930s, the Mapparium is the first of its kind. If you aren’t dazzled by its sheer size, then the lighting system and acoustics will. There are 206 LED light fixtures able to produce nearly 16 million color combinations.
Being a sphere, the Mapparium produces some of the weirdest echoing. Stand at the center of the chamber and say something; you’ll be astonished when your voice echoes loudly. Don’t say anything provocative while standing at one end of the bridge because everyone at the other end will be able to hear you perfectly
