The Palazzo Pallavicini-Rospigliosi is a palace in Rome, Italy. It was built by the Borghese family on the Quirinal Hill; its footprint occupies the site where the ruins of the baths of Constantine stood, whose remains still are part of the basement of the main building, the Casino dell'Aurora. Its first inhabitant was the famed art collector Cardinal Scipione Borghese, the nephew of Pope Paul V, who wanted to be housed near the large papal Palazzo Quirinale.
The palace and garden of the Pallavicini-Rospigliosi were the product of the accumulated sites and were designed by Giorgio Vasanzio and Carlo Maderno in 1611-16. Scipione owned this site for less than a decade, 1610–16, and commissioned the construction and decoration of the casino and pergolata, facing the garden of Montecavallo. The Roman palace of this name should not be mistaken for the panoramic Villa Pallavicino on the shores of Lake Como in Lombardy.
The Casino dell'Aurora:
The palace's main attraction, beside the art gallery, is the Casino dell'Aurora. The casino was designed by Vasanzio is located overlooking the Piazza del Quirinale. On the walls are four frescoes of the Seasons by Paul Bril, and two Triumphs by Antonio Tempesta. Its ceiling displays what is considered the Bolognese painter Guido Reni's fresco masterpiece (1614). It is surrounded by a painted frame or quadro riportato and depicts Apollo in his Chariot preceded by Dawn (Aurora) bringing light to the World. The incorporated heraldic symbols were meant to link Scipione with Apollo.
The work is classically restrained and mimics poses from ancient Roman sarcophagi, many of which are part of the museum's collection. The chariot procession, which recalls the Annibale Carracci paintings in the Farnese Gallery in the Farnese Palace, shows even more restraint. There is little concession to perspective, and if anything the vibrantly colored style is an affront to the tenebrism of Caravaggio's followers, despite this being a pavilion commissioned by one of Caravaggio's early patrons, Scipione Borghese. The pergolata is decorated by Paul Bril.
The art gallery, the Galleria Pallavicini, was begun by Cardinal Lazzaro Pallavicini, and includes more than 540 paintings, designs and sculptures. Aside from the collections of the Doria-Pamphili and Colonna families, this is the largest private collection in Rome. The rooms are frescoed by Paul Brill, and a loggia in a garden is decorated with frescoes by Orazio Gentileschi and Agostino Tassi. Among the paintings that remain in the collection, following some sales and losses in previous centuries.
