The king of Naples , Carlo di Borbone , that many important monuments wanted for his Italian capital, had the idea of the construction of an hunting"  casino "  on the lovely hill of Capodimonte , seven kilometers of secular forest , choiced as royal preserve. He charged Carasale , who was, already, engaged for  the  Theatre  of San Carlo , and gave the direction of the jobs to Giovanni Antonio Medrano and Antonio Canevari . The first stone was placed in 1738 , but the construction continued for approximately twenty years cause the enormous difficulty that represented the dug transport of the piperno in the hollow ones of Pianura. Finally in 1758 the mistresses Farnese collections , inherited from Carlo for maternal way, were arranged in the wide building from the immense courtyards.
Ferdinand IV , successor of Carlo , entrusted the widening of the Reggia and the cure of the park to the architect Ferdinando Fuga.
Its classical-stately style, typical of the great European courts, and its solemn and grand structure show the celebrative and encomiastic intents of the ruling dinasty.
From 1758 to 1806, the historical and artistic cores of the Farnese collection, which Carlo di Borbone had inherited from his mother Elisabetta, the last descendant of the Family, and that had reached Naples from the formerly Farnese estates of Parma and Piacenza, and from the Roman palace of the family, were placed in the Neapolitan palace.
With the transfer of all the collections of art in the Palace of the Studies, current National Archaeological Museum , happened during French decade ( 1806-15 ), the Reggia became residence of Giuseppe Bonaparte and of Gioacchino Murat . The residential function comes confirmed from Ferdinand , returned from the sicialian exile  in 1815 , that it undertakes new jobs in the palace and the park. A formation of painters, scultori and craftsmen are calls to decorate rooms of the Reggia , in particular the Hall of the Festivities and to half century the palace finally is completed.
The destiny of the Reggia did not change with   the accession of the Savoia family, after the reunion of Italy. At the end of the eighteenth century, a true Gallery of Modern Art, made up of paintings and sculptures by living Neapolitan artists, was created in some halls of the palace.
In 1920, the palace passed from the Crown to the State property. The revival of its exhibit function took place in 1957, when, after the necessary works of restructure and functional adjustment, the Museo e Gallerie Nazionali di Capodimonte opened to the public.

The Roman collection
At the dead  of Paul III in the 1549 politics of increment of the collections come continued by the grandsons Alexander ( 1520-1589 ) and Ranuccio ( 1530-1565 ), both cardinals. In particular, the first one confers ulterior impulse to the collections, surrounding himself of a formation of artists (from Michelangelo to Tiziano , from El Greco to Bertoja , Salviati to Guglielmo Della Porta ), whose works today constitute the essence of the collection. Cardinal Odoardo ( 1573-1626 ) carries out new acquisitions, demands works of art from the Parmesans property , becomes in the 1600 beneficiary of the collection of Fulvio Orsini , librarian and artistic councilman of the uncle Alexander . After its dead , in the 1626 , the Palace slowly remains uninhabited and empty; remains the great statuaria , the antiquity collections - than the cardinal Alexander it had legacy to the building - let alone a residual number of paintings that thought of smaller interest for the collection Parmesan who went itself constituting in the emilian duchy  in the second half of the 1600's.

The Parmesan collection
With the duke Ranuccio the branch Parmesan of the collection acquires greater thickness. The inventory of its assets, written up in the 1587 , lists a group of forty  pictures, for more than school Parmesan between which " the Galeazzo Sanvitale " of the Parmigianino and " the Zingarella " of the Correggio . A decisive increment happens with the requisitions of the assets of feudatari rebels ( 1611 ), when they reach in the collections of family painted of Giulio Romano , of the Correggio , and  Bruegel While despoliation of the Roman collection continues , in the palace of the Garden of Parma , of recent restored, meets a considerable patrimony of art of extreme importance. In the last decade of the century, Ranuccio II (1646-1694 ) matured the idea to transfer the best pieces  of this collection in " a Gallery " devised in the cinquecento Palace of the Pilotta in Parma , where 329 paintings find placing . The successories of Ranuccio II , Francisco ( 1694-1727 ) and Antonio ( 1727-1731 ), increased the collections with one series of purchases carried out from the territory of the Duchy. Great part of this material, constituted gives beyond 170 paintings , meets in the Apartment of the Pictures , other expositive nucleus, distributed in six rooms. Between the paintings, many burlaps of clear ecclesiastic origin. The last one duke of Parma , Antonio , dies in 1731 . It succeeds Carlo di Borbone , son of Filippo V king of Spain and Elisabetta Farnese . From the mother he inherited, beyond to the title, the immense artistic patrimony of family. Entered in Naples in 1734 , it arranges to the transfer  all the collections of family conserved in the palaces of the Ducato of Parma and Piacenza , in the Capital of its new Reign.

The Borbone collection
With the patrimony of art inherited from the Farnese, the collectionistic activity of Carlo di Borbone is not get exausted , of his son Ferdinand IV , and  their descendants. A Coleccionism that feeds various formulas second: or with a relationship of directed customer to painters, at least to the not Neapolitan origin of prevalence, which the task is demanded to furnish (with views, landscapes, representation of customs and popular life, let alone portraits and celebrative images of the reigning monarchy) the more real situated important, between which the Reggia di Capodimonte ; or feeding, above all after the transfer of all the collections of art and antiquity in the Real Borbonico Museum , the acquisition of works of the past, to integrate how much already were possessed for hereditary right from the Farnese family . To Capodimonte , the collections entrusting to painters, of preference not Neapolitan, the celebrative images of the dynasty increase. In the years of Carl ( 1734-1759 ) and in those of Ferdinand they work for the Short artists like Giovanni Paolo Pannini , Francisco Liani , Raphael Mengs , Philipp Hackert , Angelika Kauffmann and Elisabeth Vigée Lebrun .
Beyond recovering to Rome the booty of art depredated from the French in the Reggia di Capodimonte , during convulse the facts of 1799 , the Borbone has way to acquire a important number of paintings , between which " the Atalanta and Ippomene " di Guido Kidneys and " the Landscape with the nymph Egeria " from Lorrain . Sent to Naples , these works find placing, between 1801 and 1805 , in the Gallery of the Palace of Prince di Francavilla to Chiaia . During the French decade, re-united all the collections of art and antiquity in the Palace of the Studies , the greater increments later on have to the expropriations of the patrimony of churches and convents deleted, with prevalence of works of artists of southern school.
In 1814 the negotiation, defined in 1817 set offs then , for the purchase of the articulated collections of the Cardinal Stefano Borgia (the so-called Museum of Velletri ). With this acquisition art objects enter in the borbonic western oriental collections  and,  archaeological and medioevali hand-made and modern works, like the famous "  Sant' Eufemia " from Mantegna .
From the second borbonic Restoration until the continuous Unit, the increment of the collections, with one series of acquisitions of single works, for more than Neapolitan artists or flamish, and of entire collections.
