Taunay, Nicolas-Antoine – Hôpital militaire en Italie, 1797 Château de Versailles

The picture has something of this: people, group, many, architecture, home, city, building, cavalry, landscape, street, tree, crowd, man, town, outdoors, military, woman.
Perhaps it’s a painting of a group of people in a courtyard with a building in the background and a crowd of people on the other side of the street.
