The Galleria Doria Pamphilj is one of the largest and most impressive private art collections in Rome, housed in the beautiful Palazzo Doria Pamphilj. The gallery is still owned by the noble Doria Pamphilj family, who have maintained the collection for generations. The gallery was first established by Pope Innocent X in 1644, and its extensive collection contains over 400 works of art, dating from the 15th to the 18th centuries.

Visitors can explore opulently decorated rooms filled with masterpieces by renowned artists such as Caravaggio, Raphael, Titian, Velázquez, and Bernini. The most famous piece in the gallery is Velázquez's portrait of Pope Innocent X, which is considered one of his greatest works. The collection also includes significant sculptures, frescoes, and other artifacts that provide a glimpse into the rich cultural and artistic history of the Pamphilj family.

Highlights of the gallery include the Gallery of Mirrors, inspired by the Hall of Mirrors at Versailles, featuring stunning frescoes and opulent gold decorations, and the family chapel, which contains religious artwork and is still used by the Doria Pamphilj family. The palazzo itself is an architectural marvel, with a mix of Renaissance and Baroque features that add to the immersive experience. The gallery also offers audioguides available in multiple languages, providing insight into the history and significance of the displayed works.
