Eiffel Tower under construction

Salut mes petit pois, this one has been doing the rounds on Twitter and t’internet, but thought it was worth sharing here with you…

A few petit facts interesant pour vous: The pig iron structure of the Eiffel Tower weighs 7,300 tonnes… as the tower was initial supposed to be demolished in 1909, and as a demonstration of the economy of design, if the 7,300 tonnes of the metal structure were melted down it would fill the 125-metre-square base to a depth of only 6 cm. And secondly, depending on the ambient temperature, the top of the tower may shift away from the sun by up to 18 cm because of thermal expansion of the metal on the side facing the sun.

And for all those of you who thought you were going to get a glimpse of the actual construction… Bien, et Mange tout alores!
