How can one not include a picture of the Eiffel Tower in a blog predominantly about Paris?
Built in 1889 it was due to be demolished in 1909, but its utilisation as a radio tower "saved its life". It is now the most visited monument in the world with 7 million visitors recorded in 2011. Once sold as scrap to a metal dealer by a con artist and having also been joined in "holy matrimony" to one Erika von Tour Eiffel, la tour has had an interesting life.
One last fact about the tower ... did you know that it is approximately 15 cm taller on a hot day than when the weather is icy?
