Sadovnikov, Vasily. Wacht-Parade Cavalry Regiment in front of the Winter Palace Hermitage ~ part 11

The picture has something of this: architecture, picture frame, decoration, ornate, antique, vintage, retro, building, design, city, baroque, castle, artistic, wall, style.
Perhaps it’s a painting of a group of people on horses in front of a building with a horse drawn carriage in the foreground.
