Whispering Gallery, Architectural marvel in New York City
The Whispering Gallery is located within the confines of Grand Central Terminal.
This acoustic anomaly was unintentionally created during the Terminal's construction in the early 20th century.
Visitors often come to experience the mysterious whispering phenomena firsthand.
Stand at one diagonal arch and whisper, a friend at the opposite corner will hear you clearly.
The gallery is famed for its peculiar acoustics allowing whispers to travel over a great distance.
