Eiffel Tower is named after the engineer Gustave Eiffel, whose company designed and built the Tower. Constructed from 1887-89 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.
The Eiffel Tower is the most visited paid monument in the world; 6.91 million people ascended it in 2015. The tower is 324 metres (1, 063 ft) tall, about the same height as an 81- storey building, and the tallest structure in Paris. Its base is square, measuring 125 metres (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.
The tower has three levels for visitors, with restaurants on the first and second levels. The top level’s upper platform is 276m (906 ft) above the ground- the highest observation deck accessible to the public in the European Union.
