The Eiffel Tower is an iconic symbol of France, located on the Champ de Mars in Paris. Constructed from 1887 to 1889 as the entrance to the 1889 World's Fair, it was initially criticized by some of France's leading artists and intellectuals for its design, but has now become a global cultural icon of France and one of the most recognizable structures in the world. Designed by Gustave Eiffel and his engineers, it is a wrought iron lattice tower, standing 300 meters tall. The Eiffel Tower is the most-visited paid monument in the world and has three levels for visitors. The first and second levels have restaurants and shops, while the top level's upper platform is 276 meters above the ground – the highest observation deck accessible to the public in the European Union. The tower is illuminated each evening, making it a striking feature of the city's skyline.
