d’Orsay Gangway
On the Left Bank of the Seine in Paris, is the Musée d’Orsay, housed in the what was once the Gare d’Orsay, a Beaux-Arts style railway station completed in 1900. This museum displays mainly French paintings, sculptures, furniture, and photography.
It is a long, tiered glass-roofed structure with a magnificent gilt clock at one end. Upstairs there are two massive glass clocks whose faces gaze across the Seine to the city on the opposite bank, with views all the way to the Basilica of the Sacré-Cœur on the Montmartre hilltop in the distance.
This photo is of an upper level walkway, showing the elaborately detailed arched walls curving up to the glass ceiling.
