Watteau, François-Louis-Joseph – La Grand’Place de Lille pendant le siège, octobre 1792 Château de Versailles

The picture has something of this: people, group, many, woman, man, church, wear, mammal, cavalry, kneeling, position, building, indoors, architecture.
Perhaps it’s a painting of a group of people standing in front of a building with a clock tower in the background and a crowd of people in the foreground.
