The Galleria in Milan, Italy was opened in 2007 and it claims to have a seven star certificate from SGS Italy2008.[21] However the SGS Italy (not the official tourism agency) only has five stars in the general hotel stars categorization, with the full title of the certificate being left unknown, just as the renewal process is unknown. Overall, as no traditional organization or formal body awards or recognizes any rating over five-star deluxe,[22] such claims are predominantly used for advertising purposes.
