London- Ranelagh, the Interior of the Rotunda, 175 Canaletto (Giovanni Antonio Canal) (1697-1768)

The picture has something of this: architecture, building, ancient, arch, column, people, dome, group, city, bedrock, monument, tower.
Perhaps it’s a painting of a large building with a lot of people standing in the center of the building and people standing around the building in the middle.
