Visitors here are silhouetted against the Great Clock at the Musee d'Orsay. The museum is housed in a former rail station and hotel; the clock is visible from quite a long stretch of the opposite bank of the Seine.
Visitors to the Museum's cafe often stop to enjoy the view from behind the clock while visiting the museum's collection. The Museum is the official home of most of the French government's collection of art spanning the early 19th to early 20th centuries, and including some of the world's deepest collections of works by the Impressionists, their immediate predecessors and influences, and then the movements influenced by them.

Above, how the clock looks from the outside; the Paris-Orleans reference is to the Paris-Orleans Railway that built the Gare d'Orsay in 1900 as a Paris terminal for its trains. The picture below is of the clock that hung over the train platforms and today is part of the museum's decor.
