When the Eiffel Tower was completed in 1889, it was the tallest building in the world. With 18,000 metallic parts and 2.5 million rivets, it was a true feat of engineering - the perfect centerpiece for that year’s World’s Fair. But Alexandre Gustave Eiffel's tower has as many fans as it did haters.
However, over time, the Eiffel Tower has become a universally beloved icon: it's now the most visited paid tourist attraction in the world. The fact is: no trip to Paris is complete without a visit to the Eiffel Tower.
