 He was soon replaced by another legate in 1740, and he retired to Piacenza, where in 1730 Clement XII appointed him administrator of the hospital of San Lazzaro, a medieval foundation for the benefit of lepers.Since leprosy had nearly disappeared in Italy, Alberoni obtained the consent of the pope to suppress the hospital, which had fallen into great disorder, and replaced it with a seminary for the priestly education of seventy poor boys, under the name of the Collegio Alberoni, which it still bears.The Cardinal's collections of art gathered in Rome and Piacenza, housed in his richly appointed private apartments, have been augmented by the Collegio.
