​ALESSI, GALEAZZO (1512–1572), Italian architect, was born at Perugia, and was probably a pupil of Caporali. He was an enthusiastic student of ancient architecture, and his style gained for him a European reputation. Genoa is indebted to him for a number of its most significant palaces, and specimens of his skill may be seen in the churches of San Paolo and Santa Vittoria at Milan, in certain parts of the Escurial, and in numerous churches and palaces throughout Sicily, Flanders and Germany.
