Architectural Capriccio with a Preacher in the Ruins Giovanni Paolo Panini (1691-1765)

The picture has something of this: people, group, architecture, city, building, sky, man, outdoors, bedrock, monument, street, column, fountain, ancient, tower.
Perhaps it’s a painting of a group of people standing in front of a building with a obelisk on the other side of the building and people sitting.
