Mapparium at the Mary Baker Eddy Library
A three-story stained-glass globe from 1935 creates one of Boston’s strangest interior experiences, allowing visitors to stand inside a historical world map. The visit is brief and geographically convenient near Symphony Hall, making it a good hidden cultural addition rather than a full museum block.
