There I was …
One mysterious morning I arrived at Grand Central early. One scene in my book is set in the whispering gallery (right in front of the Oyster Bar), so I had to stop by. It’s part of my Grand Central routine now–visit the whispering gallery. I was shocked to find I was the only one there. For just a moment or two, I was the only person in the whispering gallery, in Grand Central Station, in the middle of New York City, the busiest city in the country. It was magical. I had just enough time alone to take this one picture.
The whispering gallery is one of many wonders in Grand Central Station. (I know, the real name is Grand Central Terminal, but everyone seems to call it Grand Central Station anyway.) The current station opened in 1913 and is the third of three that have been located at that site. The first was constructed in 1871, just six years after the end of the Civil War.
So how—and why—does a whispering gallery work? If you stand facing the wall in any of the four corners, and whisper, your words will be carried to the corner diagonally across from you and can be heard by someone in that corner. It doesn’t matter if there are crowds of very noisy people in the gallery. Your whispered words will come through. Also, two conversations can go on at once when people are standing in all four corners. The signals won’t get crossed. The science of a whispering gallery has to do with the way sound waves (called whispering gallery waves) are carried along the surface of a circular wall or overhead in a gallery shaped like an ellipse (a regular oval).
The curved ceiling in the Grand Central whispering gallery is constructed of Guastavino tile, named after the Spanish building engineer Rafael Guastavino who invented this type of interlocking terracotta tile for use in arches and architectural vaults.
Most sources I’ve looked at say the space was not designed to be a whispering gallery. It was simply a “happy accident.” I love the fact that there is no big plaque or poster explaining what happens there. You just have to learn about it by watching, or reading, or being told by someone else. Maybe in a whisper.
