Priebke, 95, is serving a life sentence under house arrest for his role in the World War II Nazi massacre of 335 Roman men and boys, including 75 Jews.
According to local media, several people in the audience reacted by shouting "for shame!" Local politicians and Jewish representatives quickly condemned the appearance, with some accusing pageant organizer Claudio Marini of using wartime tragedy as a publicity stunt.
Marini had prompted sharp criticism earlier in the year when he attempted to name Priebke to the pageant's jury, claiming he was doing so as part of a "peace process."
