They explain its construction, from the foundations to the metal structure, as well as its 103,000 tons of framework incorporating elevators and other facilities. They take us into the machinery of the west pillar to discover the old hydraulic elevators from 1899. Constantly undergoing maintenance, the tower requires the services of mountaineers, painters, and engineers to replace its components and repaint it every 7 years. With its 17 layers of paint and its role as a radio and television transmitter, the Eiffel Tower is much more than just a tourist attraction. "It's Not Rocket Science," the science and discovery magazine presented by Fred, Jamy, and Sabine.
