I'm high on the Bernini and the Goya.
I'd nominate Bernini's piazza except it was never finished per plan, and I liked the plan.
I'll nominate
piazza di Campo in Siena, c. 1194/1262, born of an etruscan temple-arena-market complex, then a roman market (fora boaria), and a medieval market.. at the confluence of two hills.
The best article I've seen on it was in italian in the Bell'Italia magazine and gave elaborate sections/plans of it over centuries. Not easy to quote.
I like it for its accretion. I like it for its usability, I like it for the way it works for the city, I like it for the light. I like it for its political savvy very early (the nine) and I like it for a saint preaching (don't get me going) St. Bernardino - and activity within the space, more or less. People shot/executed there in the war, don't make me chase a link - I read that in a book of Bererson. (sp)
There was early bullfighting, perhaps.
The 'nine' is represented in the shell design..
So, a confluenced place that had a design that related to the city.
T0 quote myself quoting Fabiani (somewhere in an old biblio), Fabiani describes a sermon St. Bernard preached in the campo in 1427, chastising women for talking during mass by imitating voices of the animals:
"ca, ca, ca" for the goose;
"cia cia, cia", for the magpie, and
"qua, qua qua" for the frog.
Well, I'll leave this. I'm more interested in how the space works for a city, and how the bull fights and palios have worked out re rivalries.
