Antonio da Sangallo the Elder

Antonio da Sangallo the Elder (c. 1453 – December 27, 1534) was an Italian Renaissance architect who specialized in the design of fortifications.

Antonio da Sangallo was born at Florence.

His father Francesco Giamberti was a woodworker, and his brother Giuliano da Sangallo and nephew Antonio da Sangallo the Younger were architects. To a great extent he worked in partnership with his brother, but he also executed a number of independent works. As a military engineer he was as skilful as Giuliano, and carried out important works of walling and building fortresses at Arezzo, Montefiascone, Florence and Rome. His finest existing work as an architect is the church of San Biagio at Montepulciano, in plan a Greek cross with central dome, "the first of the great cinquecento domes to be completed". and two towers, much resembling, on a small scale, Bramante's design for St. Peter's Basilica.

He also built a palace in the same city, various churches and palaces at Monte San Savino, and, at Florence, a range of monastic buildings for the Servite monks. Antonio retired early from the practice of his profession, and spent his latter years in farming.

His other works includes he church of San Biagio at Montepulciano, the Forte Sangallo of Civita Castellana and the Old Fortress of Livorno.
