Premazzi, Luigi – Kazan Cathedral on the Nevsky Prospect in St. Petersburg. Sketch Hermitage ~ part 10

The picture has something of this: people, building, architecture, administration, group, military, many, town, war, city, vintage, cavalry, column, soldier.
Perhaps it’s a drawing of a building with a dome on top of it and people walking around in front of the building and a horse and buggy.
