The Tower was opened to visitors on May 6,1889. Gustave Eiffel’s design was chosen from among 107 that were submitted to the World’s Fair design competition. However, many Parisians, especially artists, did not like his design and protested the tower’s construction. They thought it would be an eyesore, but once it was built, most Parisians soon loved the tower. The tower is made of iron and weights over 10,000 tons. It is 324 meters tall, including antenna at its top, and has a staircase with 1,665 steps. There are also elevators to take visitors to the top platform where there is a panoramic view of Paris. The original elevators, now computerized, are still in use. Over 60 tons of paint are applied to the tower every seven years to keep it from rusting. The Eiffel Tower has become a symbol of Paris. It is the most recognized monument in Europe, and many people think it is an architectural masterpiece. Over 250 million people have visited it since May of 1889.
