I've never seen this shrine in person and have no idea where in Venice it is. I'm hoping that someone who reads my blog knows!
A friend of mine took this photo in 2003 - with film (remember film?) and thus she doesn't have the digital clues of date/time/what other photos were taken close to this one.
It was her first and only trip to Venice, and she doesn't know what sestiere she was in (in fact, she said that she might have taken it on Murano since she spent part of a day out there).
Here is the uncropped photo below. Please let me know if you have seen it!
