The Musée d'Orsay was very nearly demolished. Built as a railway station for the 1900 World's Fair, the Gare d'Orsay saw its platforms grow too short for modern trains within decades, and by the 1970s the vast Beaux-Arts hall stood under threat. Instead of the wrecking ball, France filled it with the art its own century had first refused. Since 1986 the great vaulted nave, its glass roof flooding the space with light, has held the world's richest gathering of Impressionist and Post-Impressionist painting — Monet, Degas, Cézanne, Van Gogh, Gauguin — the years from 1848 to 1914.
You enter beneath an iron-and-glass ceiling that still feels like a station, then climb to the upper floor where the paintings hang close and the light turns soft. On the top level, an enormous transparent clock face frames Montmartre and the white domes of Sacré-Cœur beyond; you stand behind the glass with the city showing through the numerals. Below, the sculpture-lined aisle runs toward a golden clock at the far end, still marking the hour as trains once did. Crowds cluster at Van Gogh's swirling self-portrait, while quieter rooms hold Degas's dancers caught mid-stretch.
