Paris just wouldn't be Paris without the Eiffel Tower. Designed by Gustave Eiffel for the 1889 World Fair, at 300 meters (984 feet) it was then the world's tallest building. Not everyone was happy when it was first built; many considered it an eyesore and wanted it pulled down, but today it is one of the world's most visited monuments. The first and second floors can be reached using the stairs, and elevators take visitors to the magnificent view at the top.
