Parade at the Palace Square in Saint Petersburg Adolphe Ladurner (1798-1865)

The picture has something of this: people, group, cavalry, many, street, man, city, child, building, seated, wear, ceremony, woman, group together, castle, architecture.
Perhaps it’s a painting of a group of men standing in front of a building with a horse and carriage in the foreground and a crowd of people in the background.
