Galeazzo Alessi (1512 – December 30, 1572) was an Italian architect from Perugia, known throughout Europe for his distinctive style based on his enthusiasm for ancient architecture. He studied drawing for civil and military architecture under the direction of Giovanni Battista Caporali.
For a number of years he lived in Genoa. He was involved in the lay-out of the streets and the restoration of the city walls, as well as being responsible for many of its impressive palazzi, now a part of the World Heritage List. His work can be found in many other Italian cities, including in Ferrara, Bologna, Naples and Milan, where he designed the facade of Santa Maria presso San Celso. With Vignola, he designed the Basilica of Santa Maria degli Angeli in Assisi, the seventh largest Christian church at the time. Elsewhere in Europe, he designed churches and palaces in France, Germany and Flanders. He produced designs for El Escorial in Spain, but age and health prevented him from carrying them out.Rocca Paolina, remodelling
