Palazzo col piercing

"Don't forget to keep your nose up while you're strolling around the city center: you can't miss this historical 18th-century building with a literal piercing! No, you're not hallucinating: this art installation (named "Baci Urbani", Urban Kisses) represents the contrast between history and modernity and was meant to be temporary, but the citizens loved it so much that it's still there up to this day. On both sides of the building, you can see a few blood drops in two colors: red (the blood of the labor class) and blue (the royal blood). This duality has long been engraved in Turin's history and can be perceived up to this day."
