In 1569, Pius V made the Zagarolo estate, belonging to the ancient Colonna family, into a duchy. The prestige of the Colonna family derived notably from their gens Julia lineage, the fact that they had been key players in the struggles between the Guelphs and the Ghibellines against the Orsini in the 12th and 13th centuries. They could already boast cardinals amongst their numbers by the late 12th century (Giovanni in 1193) and a Pope in the 15th century, when Oddone ascended to the Papal Throne as Martin V in 1417.
The restoration work on the old Zagarolo Palace and the entire surrounding area, a rich livestock and arable farming centre, dates back to the time the duchy was created in the second half of the 16th century. The ducal palace modified the original fortified mediaeval centre with the addition of two long wings facing the centre—which still define its shape—which was restructured to suit the palace. In 1622, the entire estate was sold to Cardinal Ludovico Ludovisi, who further embellished the palace. It was then taken over in 1670 by the Rospigliosi family, who completed the ground-floor decorations.
The 16th-century interior decoration is a compendium of themes exalting antiquity, according to a master plan for the renovatio of Antiquity, intended to legitimise the power of the Colonna family, recent undertakings by family members (victory against the Turks in Lepanto in 1571) and the family's virtues. In the first two rooms, paintings by Giovanni Bianchi of Reggio Emilia depict the celebrations of the victory at Lepanto (1571), the battle against the Turks where Marcantonio Colonna fought at the head of the papal fleet. The battle was hailed as a victory of the Church a sentiment underlined by the allegories of the theological virtues (Faith, Hope and Charity) and the cardinal virtues (Prudence, Fortitude, Justice and Temperance). The "imprese" of the Colonna family are also displayed in several places: the two-tailed mermaid, elements from the coat of arms (a crowned column) and an image of rushes emerging from the waves with the motto "Flectimur non rumpimur undis" ("we are bent but not broken by the waves").
In other rooms on the ground floor, painted by the school of Federico Zuccari and dating back to the last years of the 16th century, landscapes with ruins alternate with coats of arms, grotesques and allegorical figures. Particularly noteworthy is the vaulted room with figures of Victory and Hope.
