The Palazzo Colonna is a palatial block of buildings located in central Rome in Italy. Found 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 who have continued to develop this stunning and unique series of buildings. The first part of the palace dates from the 13th century, and tradition goes that the building hosted Dante during his visit to Rome.
The main gallery was completed in 1703 and the exceptional Colonna art collection was acquired after 1650 by both the cardinal Girolamo I Colonna and his nephew, the Connestabile Lorenzo Onofrio Colonna. It includes works by Lorenzo Monaco, Domenico Ghirlandaio, Palma the Elder, Salviati, Bronzino, Tintoretto, Pietro da Cortona, Annibale Carracci, Guercino, Francesco Albani, Muziano and Guido Reni. Ceiling frescoes by Filippo Gherardi, Giovanni Coli, Sebastiano Ricci, and Giuseppe Bartolomeo Chiari celebrate the role of Marcantonio II Colonna in the battle of Lepanto (1571).
