Gustave Eiffel chose this "invocation of science" because of his concern over the protests against the tower . The engravings are found on the sides of the tower under the first balcony, in letters about 60 cm high, and originally painted in gold . The engraving was painted over at the beginning of the twentieth century and restored in 1986--1987 by Société Nouvelle d'exploitation de la Tour Eiffel, the company contracted by the city of Paris to operate the Tower . The repainting of 2010--2011 restored the letters to their original gold colour . </P> <P> There are also names of the engineers who helped build the tower and design its architecture on the top of the tower on a plaque, where a laboratory was also built . </P>
