Hubert Robert – Capriccio with Pantheon and Porto di Ripetta Liechtenstein Museum (Vienna)

The picture has something of this: architecture, people, temple, building, water, city, ancient, outdoors, group, fountain, column, sculpture, daylight, tourist, sky.
Perhaps it’s a painting of a group of people on a boat in a body of water with a building in the background and people on the other side of the water.
