The Eiffel tower was constructed by Gustave Eiffel for the world`s fair of 1900. In that time there were no similar metal constructions in the world. Its height was 324 meters. And until 1931 it was the highest construction in the world and nowadays it is called a symbol of Paris.
Annually the tower is visited by about 5-6 million of tourists. It has three levels for visitors. There are restaurants (and skating rink in winter time) at the lower levels. And you can enjoy a splendid view of almost all Paris from its uppermost level.
