It is made of lattice-shaped wrought iron with 20,000 lights. The Eiffel Tower was built for $1.5M in 1889. If we inflation adjust this original cost using CPI, we get $44M. According to a 2012 study by the Chamber of Commerce of Monza and Brianza in northern Italy, it is worth $510 billion.
Is the Eiffel Tower privately owned?
Today, the City of Paris owns the Tower and has entrusted its management to a development company (SETE: Société d'Exploitation de la Tour Eiffel) of which it owns 99% of the capital. Bertrand Lemoine is an architect, engineer and historian.
