The picture was taken in the park by the tower around mid-June in 2010. The tower is one of the tallest buildings in Europe, and was the tallest man-made structure for several years. The Eiffel Tower was originally built for the World fair in 1889, but was kept as several other pieces for World fairs have. It has three levels for visitors, and you can walk to the 1st and 2nd level, or go by lift/elevator to the 1st, 2nd or 3rd level. (I walked up one or two of the levels when I was 8, and have since had a slight height-phobia.)
When France was invaded in the Second World War, the cables for the lifts were cut. Apparently this was so that Hitler had to use the stairs if he wanted to climb it. He never did, and the cables were allegedly fixed shortly after the Liberation of Paris.
