Return Of The Bucentoro To The Molo On Ascension Day detail Canaletto (Giovanni Antonio Canal) (1697-1768)

The picture has something of this: architecture, building, city, canal, river, famous, tower, town, water, landmark, sky, tourist, historic, urban, outdoors, ancient.
Perhaps it’s a painting of people on a gondola in front of a large building with a clock tower in the middle of the picture and people on the other side of the gondola.
