Fat Thursday
Upon a shoot-out orchestrated by Tristano Savorgnan right in the centre of Venice, in which Alvise della Torre jr. (the youngest son of the leader of the strumieri faction murdered during the "Fat Thursday massacre") and some members of the Colloredo family were killed, the governor of Venice confiscated the Savorgnan family's assets in 1549 and destroyed their family palace in Udine, leaving its ruins as a warning in what was called "place de ruine" ("square of the ruins" in Friulian language, or "piazza delle rovine" in Italian; now "Venerio Square", after the Udinese metereologist Gerolamo Venerio).
