A three-story stained-glass globe built in 1935 that visitors walk through on a glass bridge, experiencing the world as it was politically mapped at that moment — a genuinely singular architectural and historical artifact. The acoustics create a whispering-gallery effect where sounds travel across the sphere in uncanny ways. Guided tours run throughout the day and last about 30 minutes. It is consistently underrated and rarely crowded despite being steps from the Prudential Center.
