Like most folks who haven't been to Venice, before I went I assumed that the famous Campanile was "about the same size" as so many of the other belltowers in the city. It's hard to get a good perspective, unless you see it in-person.
That bell tower is huge. You can see it from islands in other parts of the lagoon, and depending on the angle, you can see it from several points within the city.
Here's a shot taken from just the right point in Bacino Orseolo.
You can just see the top of the tower.
One thing I've yet to do is take a tour up to the top of the Campanile.
Maybe next time I visit, if I can break away from all the rowing.
