The Cathedral of Mantes, 1865-1869, Musee Saint Denis, Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: tree, landscape, fall, wood, nature, outdoors, leaf, water, vintage, light, river, park, environment, dawn, decay.
Perhaps it’s a painting of a castle next to a body of water with trees in the foreground and a man sitting on a bench.
