Schultz, Karl. Kind of a monument to Nicholas I on St. Isaac Square Hermitage ~ part 13

The picture has something of this: architecture, building, city, outdoors, statue, baroque, sculpture, town, square, street, monument, sky, administration, fountain, landmark, castle.
Perhaps it’s a painting of a statue of a man on a horse on a pedestal in the middle of a square with people walking around and buildings in the background.
