The Fortress of Senigallia rises up near the Adriatic coastline, which has been a strategic position since ancient times against the enemies who came from the sea. On the remains of the Roman era, it was built the medieval coastal sighting tower, which was enlarged and surrounded by defensive walls that became wider and wider over the centuries.
The current appearance of the Fortress dates back to the Renaissance period: it was built between 1476 and 1482 by Giovanni Della Rovere, nominated Lord of Senigallia and Vicar of Mondavio by Pope Sisto IV, who was at the time his uncle Francesco Della Rovere.
The Duke Giovanni Della Rovere commissioned the most excellent architects at the time to build his residence: Luciano Laurana, who had already given his services to the Ducal Palace of Urbino, designed the residential part of the fortress; Baccio Pontelli, a talented military architect, managed to end Laurana's project by realising also the defensive structure.
