The Gallery was brought into existence, in 1651 by a Papal brief issued by Giambattiste Pamphilj, elected to the papal throne in 1644 as Innocent X. He placed the paintings and furnishings of Palazzo Pamphilj in Piazza Navona under the encumbrance of entail. The collection was enlarged later in 1647 by marriage to the Borghese. Today the gallery has a fairly large collection of around 400 paintings, including works by Rapheal, ?Tintoretto, Titian, Caravaggio, Bernini and some Flemish masters. It most famous painting is by Velazquez’s portrait of Pope innocent X.
