Karl Friedrich Schinkel (1781 – 1841) – Castle by the River Alte und Neue Nationalgalerie (Berlin)

The picture has something of this: tree, landscape, dawn, sunset, wood, light, park, nature, fall, outdoors, sky, fog, lake, sun, evening, reflection, house, water.
Perhaps it’s a painting of a wooded landscape with a river in the distance and a castle on the other side of the lake in the middle of the painting.
