Eiffel Tower is an iron lattice tower on the square of the God of war in Paris, France. It was named after engineer Gustave Eiffel, whose company designed and built the tower.

Founded from 1887 to 89, it is the entrance to the 1889 World Expo. At first, it was criticized by some leading French artists and intellectuals for its design. However, it has become a global cultural symbol of France and one of the most famous buildings in the world. The Eiffel Tower is the most visited monument in the world. In 2015, 6.91 million people climbed the heights.

The tower, 324 meters (1063 feet) high, is the tallest building in Paris, the same height as an 81 story building. Its bottom is a square, 125 meters (410 feet) long on each side. In the process of construction, the Eiffel Tower surpassed the Washington Monument as the world's tallest man-made structure. The castle remained 41 years old until the completion of Chrysler tower in New York in 1930. Thanks to the addition of radio in 1957, it flew high above the top of the tower and is now 5.2 meters (17 feet) taller than the Chrysler building. In addition to the transmitter, the Eiffel Tower is the second highest independent building in France after the Millau Viaduct.

The tower is divided into three floors, with restaurants on the first and second floors. The upper platform on the top floor is 276 m (906 ft) above the ground – the highest viewing platform accessible to the EU public. Tickets can be purchased to climb stairs or to the first and second floors. The climb from the ground to the first floor is more than 300 steps, so is the climb from the first floor to the second floor. Although there are stairs on the top floor, they are usually only accessible through elevators.
