Bonstedt, Louis Franz Karl – Cameron Gallery and Grotto on the shore of the pond Tsarskoselski Hermitage ~ part 02

The picture has something of this: tree, water, lake, people, river, outdoors, daylight, recreation, park, landscape, leisure, architecture, summer, city, building, sky, nature.
Perhaps it’s a painting of a lake with a boat in the foreground and people on the other side of the lake and a large white building in the background.
