Of Sever Hall, Harvard Yard (next to yesterday's library). If you whisper directly into the bricks on one side of the arched doorway, you can hear it on the other side of the arch, 12 feet away.

Fun Sever story: Writer Gertrude Stein once took a class from psychologist William James (Henry's brother) and during a final exam in Sever, wrote in her exam book: "Dear Professor James, I am so sorry but really I do not feel like an examination paper in philosophy today.” She received a response the next day: “Dear Miss Stein, I understand perfectly how you feel. I often feel like that myself.” James gave her the highest mark in the class.
