The Eiffel Tower isn’t just a symbol of Paris; it represents all of France. Gustave Eiffel designed this 1,050-foot (320-meter) "Iron Lady" to celebrate the 100th anniversary of the French Revolution. It used to be the tallest structure in the world! Though it's now overshadowed by Dubai’s Burj Khalifa and The Shard in London, the Eiffel Tower remains one of the most recognizable landmarks ever. Whether you admire it from a distance or visit its three observation levels for amazing city views, the Eiffel Tower is a must-see.
