The Centro district was one of the four districts of Rome during the Renaissance era. The district was characterized by its large cityscape, tall buildings, and dense population, and it was also home to the Pantheon, Mausoleo di Augusto, the Campidoglio, Tiber Island, and other major landmarks in the city. During the papacy of Pope Alexander VI (1492-1503), the district was overseen by Borgia towers and Papal troops, but the district was liberated from Borgia control by Ezio Auditore da Firenze, who killed the captains and blew up the towers. Soon, the decrepit old buildings of the district were revitalized and transformed into newer shops.
