The best-known of Rodin's works, The Thinker (1880–1882), sits outside the museum in the entry courtyard. Visitors once entered through a cast of The Gates of Hell, located at the main entrance to the museum, which is no longer used. This massive 5.5-m-tall bronze doorway was originally created for the Museum of Decorative Arts (which was to have been located in Paris but never came into existence).
