3/4. The World’s Largest Tiffany Clock + Information Booth Clock

Grand Central Terminal is home to the world’s largest Tiffany Clock, operating at 13 feet in diameter. Originally installed in 1914, the clock continues to overlook 42nd Street to this day. It was designed by French sculptor Jules-Felix Coutan, and is surrounded by sculptures of Hercules and Mercury that were carved by the John Donnelly Company of Minerva.

Since its installation, the clock has undergone serious repairs. Its most serious restoration took place in 1992 by Rohlf’s Studio, a process which took twelve years to complete. In addition to restoring the original clock, the Studio was required to replicate missing parts and reinstall the clock piece by piece. With its stunning and elaborate exterior, it’s difficult to imagine what it may look like from the inside. Luckily, these photos give us a glance inside.

Additionally, inside Grand Central Terminal sits one of New York City’s most recognizable clocks, which sits atop the central information booth. There’s a common myth that it may be worth more than $10 million because of its four milk-glass (or opaline glass) faces. Regardless of its real worth, it’s certainly one of the city’s most iconic clocks. For more information about New York City’s beloved transit hub, make sure to join us for an upcoming tour:
