The palazzo was once the home of Pope Innocent X (Giambattista Pamphili), and now houses one of the most refined art collections in the capital. The most famous names in Renaissance art are represented. Amongst the most celebrated offerings is Titian's Salome, a work from the beginning of his career. Also included in the Italian wing are works by Caravaggio and Guercino, a Portrait of two gentlemen by Raffaello, and the unfinished Allegory of Virtue by Correggio. There is a prevalence of Flemish names among the foreign artists, such as Brueghels and Pieter the elder.
