Here we are walking along the seafront at Civitavecchia, port of Rome. The seafront views are dominated by the massive solid structure that is the Forte Michelangelo. The fort dates from the early 1500s.
The Forte Michelangelo on the seafront of Civitavecchia was first commissioned from Donato Bramante by Pope Julius II, to defend the port of Rome. The upper part of the "maschio" tower, however, was designed by Michelangelo, whose name is generally applied to the fortress. Pius IV added a convict prison, and the arsenal, designed by Bernini, was built by Alexander VII.
Forte Michelangelo is a fortress guarding the port of Civitavecchia, in the Metropolitan City of Rome Capital.
Construction of the fortress began in 1508 and was completed in 1537 under the pontificate of Paul III, under the direction of Antonio da Sangallo the Younger. An unsubstantiated local tradition holds that the *mastio*—the fortress's main keep—was designed by Michelangelo Buonarroti, hence the name Forte Michelangelo.
History
Between the 10th and 11th centuries, a stronghold was erected in a commanding position amidst the ruins of the ancient city and its devastated port; a small settlement gradually formed alongside it, following the line of the ancient Roman road. By the 13th and 14th centuries, the port of Civitavecchia was already serving as a landing point, albeit one with poor connections and a lack of facilities. With the reorganization of the Papal States following the Council of Constance (1414–18), Civitavecchia slowly regained a coherent urban layout; its port was restored, and the city was enriched with fine buildings that contemporary sources attribute to Bernardo Rossellino.

The rediscovery of alum deposits in the Tolfa Mountains and the need to organize the export of this precious mineral drove the port's definitive revival. Restoration work was entrusted to leading architects of the papal court, including Giovannino de' Dolci, Baccio Pontelli, and Donato Bramante; it was Bramante whom Pope Julius II commissioned to design the fortress that still dominates the harbor basin today. Famous figures who visited the site included Leonardo da Vinci, who carefully studied and sketched the surviving Roman structures.
View of the Fort overlooking the ancient port. Structure
The massive Fort Michelangelo is quadrilateral in shape (with a footprint measuring approximately 100 by 120 meters), featuring four corner bastions and an octagonal keep. One of the bastions—the eastern one—bears a symbol from the coat of arms of Pope Julius II (who commissioned the fortress): an oak tree. This symbol marks the spot where, on December 14, 1508, Julius II blessed and laid the cornerstone. The bastions are named San Paolo, San Pietro, San Romolo, and San Giulio.
