Palazzo Colonna
The Palazzo Colonna () is a palatial block of buildings in central Rome, Italy, at the base of the Quirinal Hill, and adjacent to the church of Santi Apostoli. It is built in part over the ruins of an old Roman serapeum, and it has belonged to the prominent Colonna family for over twenty generations. History The first part of the palace dates from the 13th century, and tradition holds that the building hosted Dante during his visit to Rome. The first documentary mention notes that the property hosted Cardinals Giovanni and Giacomo Colonna in the 13th century. It was also home to Cardinal Oddone Colonna before he ascended to the papacy as Pope Martin V in 1417. With his passing, the palace was sacked during feuds, and the main property passed into the hands of the Della Rovere family. It returned to the Colonna family when Marcantonio I Colonna married Lucrezia Gara Franciotti Della Rovere, the niece of Pope Julius II. The Colonna family's alliance to the Habsburg power likely protected the palace from looting during the Sack of Rome (1527). Starting with Filippo Colonna (1578–1639), many changes have refurbished and create a unitary complex around a central garden.
