The Galleria Borghese houses a substantial part of the Borghese collection of paintings, sculpture and antiquities, begun by Cardinal Scipione Borghese, the nephew of Pope Paul V (reign 1605-1621). The Villa was built by the architect Flaminio Ponzio, developing sketches by Scipione Borghese himself, who used it as a villa suburbana, a party villa at the edge of Rome. Scipione Borghese was an early patron of Bernini and an avid collector of works by Caravaggio.
