Crescent moon do the show under Iron Lady's spotlight

The Eiffel Tower—or as the French call it, La Tour Eiffel—is one of the world’s most recognizable landmarks. The tower was designed as the centerpiece of the 1889 World's Fair in Paris and was meant to commemorate the centennial of the French Revolution and show off France’s modern mechanical prowess on a world stage.

The tower was built by Gustave Eiffel’s civil engineering firm in two years, two months, and five days, using 7,500 tons of iron and 2.5 million rivets. The end result of Eiffel’s hard work dominates the Parisian skyline and its stark silhouette has been emulated around the world in China, Las Vegas, Greece, and, of course, Paris, Texas.

Since opening in 1889, the Tower has welcomed over 300 million people and still welcomes almost seven million visitors a year. Despite the incredible number of people who have walked up the iron tower, there are still secrets to tell about it.
