Yes, Chrissy, was the first to guess it: a manhole cover celebrating the 150th Anniversary about Italy's Unification. Jilly appreciated the Italian style. Sonia, that I met at Torino Incontra, lives in Torino (so she had way to notice it). Dina centered the point in fact I accurately avoided to step on it. Rambling Round is right (and it's what I thought when I noticed it). Well Julie, Torino and I thank you about the compliment - this Manhole is in front of Palazzo Carignano.
MattGhm, ti ringrazio molto per i graditi complimenti che hai inteso rivolgere alle mie foto nonché per l'apprezzamento dell'atmosfera torinese.
