One of the most impressive features of the Eiffel Tower is its construction. The tower is made up of over 18,000 pieces of iron, held together by 2.5 million rivets. It took over two years to build, with over 300 workers working on it at any given time.

In addition to its impressive height, the Eiffel Tower also has three levels that can be accessed by visitors. The first level, at 57 meters, contains a small museum and a café. The second level, at 115 meters, has a restaurant and a champagne bar. The top level, at 276 meters, offers breathtaking views of Paris and the surrounding area.
