A well-known city:
Or even San Antonio?
I'm going to say Venice. At least I think that's Italian on the shopfronts...
Looks too clean, but Ensenada?
When I first saw the picture, my head went ding at "Venice" but then I realized that drucee already guessed that.
So here's my next guess is Mestre, Italy. (FYI, Mestre is a city on the mainland, just a boat ride from Venice).
is it Genoa?
Indeed you can usually tell when the concepts of democracy and citizenship are weakening. There is an increase in the role of charity and in the worship of volunteerism. These represent the élite citizen's imitation of noblesse oblige; that is, of pretending to be aristocrats or oligarchs, as opposed to being citizens.
Venice is right, but there isn't much in this picture to suggest it, with its bland architecture. What was the tip-off? The lack of cars? I guess if it were any other city in Italy there would be at least one or two Fiats casually interspersed with the people.
This little square is like numerous others about 100 yards off a tourist trail. It's a genuine center of neighborhood activity and rarely encounters tourists. I found a pizzeria with outdoor seating, and the middle-aged waitress addressed me as "Hon"; she had lived in Grand Rapids but had returned to the neighborhood where she grew up. Everyone else in the pizzeria was also a local. This was the real Italy; it could have been a million miles from the Grand Canal, but it was actually a hundred yards.
Honestly, I thought it was the same plaza square as you, ablarc, described. Wow.
I actually took a close-up picture of the white column of the white storefront in your pricture so that I could capture how high the floods have been over the many years. It was an interesting photo, but I haven't seen it for a while. I'm very sure that it's the same place.
What a small world!
