The large collection of paintings, furniture and statuary has been assembled since the 16th century by the Doria, Pamphilj, Landi and Aldobrandini families now united through marriage and descent under the simplified surname Doria Pamphilj. The collection includes paintings and furnishings from Innocent X's Palazzo Pamphilj (in Piazza Navona), who bequeathed them to his nephew Camillo Pamphilj. The Palazzo has grown over the centuries; it is likely the largest in Rome still in private ownership. The main collection is displayed in state rooms, including the chapel, complete with the mummified corpse of the family saint. However, the bulk is displayed in a series of four gilded and painted galleries surrounding a courtyard. An extensive suite of further rooms have now been converted to permanent well-lit galleries, containing the more medieval and Byzantine art in the collection. This is one of the largest private art collections in Rome with more of 400 pictures, with masterpieces by Caravaggio, Tiziano, Raphael, Bernini, Velàzquez and many other.
