Zichy, Mihaly – Parade in front of the palace Anichkov February 26, 1870 Hermitage ~ Part 05

The picture has something of this: street, people, city, square, urban, group, vintage, man, cavalry, uniform, group together, road, castle, crowd, building, tourist, many.
Perhaps it’s a painting of a group of men in uniform standing in front of a building with a horse drawn carriage.
