Le Bois Sacre Arnold Böcklin (1827-1901)

The picture has something of this: tree, winter, wood, outdoors, dawn, fall, landscape, snow, light, cold, weather, fog, road, placid, park, water, leaf, evening.
Perhaps it’s a painting of a group of people in a park with trees in the foreground and a building on the far side of the painting in the background.
