As you ascend to the roof of the Walgreens Tower at 1 Times Square, you’ll see an access door. Opening it, you’re outside, a glow emanating from atop a flight of stairs. Walk up those steps, and you’re face-to-face with a New York icon: The New Years Eve Ball. Made of Waterford Crystal and LEDs, this 12-foot in diameter ball weighs nearly 12,000 pounds and is completely computer controlled. See our behind-the-scenes look at the Times Square Ball with Atlas Obscura.
