The Eiffel Tower is one of the most famous structures in the world. It was named after Alexandre Eiffel whose team of engineers designed it. It cost £260,000 to build in 1889 with most of the money being provided by Eiffel himself and the French state. For over forty years it was the highest structure in the world. The structure is largely composed of triangulated sections and this allowed the engineers to build the tower so high. It was originally looked upon as a temporary structure, built for the 1889 Worlds Fair.
