The Eiffel Tower in Paris France, took two years to build and was completed in time for the 1889 World Fair on the 100th anniversary of the end of the French Revolution.
At 324 metres tall, Alexandre Gustav Eiffel's award-winning design was, at the time of completion, the tallest man made structure in the world. The tower was surpassed, however, in 1930 upon completion of New York's Chrysler Building.
Despite its modern day popularity, however, the Eiffel Tower was almost demolished and scrapped at the start of the 20th century, only to be saved at the 11th hour to be used as a communications mast.
The Eiffel Tower is Paris, France's, main tourist attraction, with millions of visitors paying a small fee to ascend the tower to one of three levels each year.
Visitors can pay to either take an elevator or walk over 300 steps to reach the tower's first and second levels where restaurants await on each level.
The tower's third level can only be accessed by the lift system, but is worth the trip as it affords visitors a stunning view across the French capital's skyline.
As of 01.09.2011, the Eiffel Tower is the second tallest structure in France.
One member of the design team was killed during construction of the tower, which took two years, two months and five days in total.
Although there is no public access by foot to the tower's third and uppermost level, it is feasible, with 1710 steps in total.
