Musée de l'Orangerie is two oval rooms holding eight paintings of one lily pond. The first is only a few paces inside the door: the wall curves right around you, so the water has no corner and no far edge. Its four paintings run from morning through clouds and green reflections to a setting sun. The second room is darker, with willow branches over green, blue and violet water, and it ends in a painting seventeen metres long. Nothing else hangs in either room.
The building was a heated winter shed for orange trees before Monet gave it the last work of his life. The day after the First World War ended he offered the state two large panels of his lily pond, a pond he had made himself in his garden at Giverny. The offer grew, and he signed the deed of gift in 1922. He designed the setting with the architect Camille Lefèvre: bare walls, no frames, daylight from the roof. He was still reworking the canvases when he died in 1926, and the rooms opened the next spring without him. A second collection of early twentieth-century painting hangs downstairs, in galleries dug under the Tuileries garden.
