The collection, formed in the XVIII century, although composed from various sources mostly originating from the Corsini family (above all from the collection of cardinal Lorenzo), is unique in the sense that it is still intact today.It shows clearly the taste of Neri Corsini, nephew of the Pope Clement XII. In 1883 the Palace was sold to the Italian State with its collection, which thus formed the basis of the Galleia Nazionale d'Arte Antica and only recently has been replaced in its original site.
