Secrets of Grand Central Terminal

Courtesy Grand Central TerminalThe world's largest Tiffany clock, measuring approximately 14 feet long. In a world of centuries-old ruins, 103 years of life for a building, may not, at first, seem so notable. But when you look at Grand Central Terminal's history, you begin to see the significance: In its lifetime, it has been used as a secret entry point into the city by past President Franklin D. Roosevelt, targeted for destruction by Adolf Hitler, and publicly defended—and saved from razing—by Jacqueline Kennedy Onassis.
