Barbacane of San Giorgio, Ferrara

History
The term barbican derives from the medieval Latin barbacanis or from the vulgar Arabic bar-al-baqara, literally "cattle enclosure", indicating a buttress, a walled reinforcement for defensive purposes.
The artifact benefited from some repairs over time thanks to the Legate of Ferrara, Cardinal Giulio Sacchetti (1627-1630), as evidenced by the engraved marble cantonal (Iulio. Card. Sacchetti Leg.) Placed above the eastern corner, while the guardhouse above cylindrical is the only testimony of the dozens of sentry boxes built during the seventeenth and eighteenth centuries along the entire fortified circuit of the city.

The bastion of San Giorgio is the result of the architectural interventions made, between 1521 and 1525, to the fourteenth-century Barbican of the same name: the surviving cylindrical guardhouse is still visible, the only testimony of the dozens of sentry boxes built during the seventeenth and eighteenth centuries along the entire fortified circuit of the city.
