The need for a banner to display at ceremonies and funerals of benefactors arose in 1927, and inspiration was taken from the banner of the Municipality of Milan, which has particularly solemn connotations. The front of the banner represents the Annunciation. On the other side, the dove is embroidered, surrounded by the heraldic insignias of the hospital's main benefactors: Sforza, Macchi, Del Sesto, Parravicini, Ponti, Secco Comneno, the municipality of Milano, Pio II Piccolomini, Pio IV Medici di Marignano, Pio XI Ratti, Cardinals Saint Carlo Borromeo e Schuster, and the Order of the Holy Sepulchre.
