Eiffel Tower Ironwork Quiz – Rivets, Paint and Puddled Iron

The Eiffel Tower was built in about two years for the 1889 World's Fair in Paris. Engineers Maurice Koechlin and Emile Nouguier sketched the first design, and architect Stephen Sauvestre refined its look.

It is made of puddled iron, a type of wrought iron, with about 18,000 parts joined by around 2.5 million rivets. Parts were made in Gustave Eiffel's workshops and assembled on site with great precision.

Painters cover it with about 60 tonnes of paint every seven years or so to stop rust. On hot days the iron expands and the tower grows a few centimeters, and 72 scientists' names are engraved around its first level.
