With 2 million visitors the first year and almost 6 million people a year today, the Eiffel Tower is a real crowd pleaser. At the crossroads of the entire world, more than 200 million visitors have come since its construction. At 300 metres (320.75m including antenna), and 7000 tons, it was the world's tallest building until 1930. http://www.paris.org/Monuments/Eiffel/
