The picture has something of this: building, architecture, water, city, park, castle, fountain, river, people, sculpture, bridge, sky, outdoors, statue, house, lake.
Perhaps it’s a painting of people on a boat in a body of water in front of a large building with columns and columns on the side of the building.
