The Eiffel Tower is a wrought-iron lattice tower on the Champ de Mars in Paris, France. It is named after the engineer Gustave Eiffel, whose company designed and built the tower.  Constructed from 1887-1889 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 it has become a global cultural icon of France and one of the most recognizable structures in the world. The Eiffel Tower is the most-visited paid monument in the world; 6.91 million people ascended it in 2015.

The tower is 1,063 ft tall, about the same height as an 81-storey building, and the tallest structure in Paris. Its base is square, measuring 410 ft on each side. During its construction, the Eiffel Tower surpassed the Washington Monument to become the tallest man-made structure in the world, a title it held for 41 years until the Chrysler Building in New York City was finished in 1930. Due to the addition of a broadcasting aerial at the top of the tower in 1957, it is now taller than the Chrysler Building by 17 ft. Excluding transmitters, the Eiffel Tower is the second tallest free-standing structure in France after the Millau Viaduct.

The tower has three levels for visitors, with restaurants on the first and second levels. The top level's upper platform is 906 ft above the ground - the highest observation deck accessible to the public in the European Union. Tickets can be purchased to ascend by stairs or lift to the first and second levels. The climb from ground level to the first level is over 300 steps, as is the climb from the first level to the second. Although there is a staircase to the top level, it is usually accessible only by lift.

The tower has two restaurants: Le 58 Tour Eiffel on the first level, and Le Jules Verne, a gourmet restaurant with its own lift on the second level. This restaurant has one star in the Michelin Red Guide. It was run by the multi-Michelin star chef Alain Ducasse from 2007 to 2017. Starting May 2019, it will be managed by three star chef Frédéric Anton.  It owes its name to the famous science-fiction writer Jules Verne. Additionally, there is a champagne bar at the top of the Eiffel Tower.

From 1937 until 1981, there was a restaurant near the top of the tower. It was removed due to structural considerations; engineers had determined it was too heavy and was causing the tower to sag. This restaurant was sold to an American restaurateur and transported to New York and then New Orleans. It was rebuilt on the edge of New Orleans' Garden District as a restaurant and later event hall.
