(b. ca. 1415, Borgo San Sepolcro, d. 1468, Roma)


Italian architect. Despite the scarce biographical information and lack of documentation, he was one of the most important figures in the architectural activities in Rome in the mid-fifteenth century.

His work was influenced by Leon Battista Alberti, with whom he shared interest in ancient architecture. He was in the service of popes Nicholas V and Pius II. From 1460, he designed to Pope Pius II the loggia for blessings of San Pietro, then c. 1467 the loggia in the façade of San Marco. For this he used travertine elements from ancient monuments, probably from the Colosseum. He played an important role in the modernization of the basilica of Santa Maria Maggiore, in the construction of the Oratorio di Sant'Andrea a Ponte Milvio, and in the design of the Palazzo Venezia, and in particular its courtyard.

Francesco del Borgo was interested in mathematics, like Piero della Francesca, also from Borgo San Sepolcro.
