The escalier Daru is part of Hector Lefuel's modifications of the Louvre in the 1850s. Lefuel was the Louvre architect from 1853 until his death in 1880. The escalier Daru was only fully completed in 1930.
Straub and Huillet give two views of the Victory of Samothrace, but do not show the stairs above which the statue was placed in 1884.
