[[Image:Quirinal Hill Luigi Rossini.jpg|thumb|right|An etching of the Hill, crowned by the mass of the Palazzo del Quirinale, from a series '''I Sette Colli di Roma antica e moderna'' published in 1827 by [[Luigi Rossini]] (1790 - 1857): his view, from the roof of the palazzo near the [[Trevi Fountain]] that now houses the [[Accademia di San Luca]], substituted an imaginary foreground garden for the repetitious roofscape.]]
The hill is the site of several other important monuments:
*The church of [[Sant'Andrea al Quirinale]] was designed by [[Gian Lorenzo Bernini]] ([]-[]), for Cardinal [[Camillo Pamphilij]] (nephew of [[Pope Innocent X]]),; it is one of the most elegant samples of [[baroque]] architecture in Rome, with its splendid interiors of marbles, stuccoes, and gilded decorations).
*The four fountains (''Quattro Fontane'') with reclining river gods (1588-93) and [[Francesco Borromini|Borromini]]'s church of [[San Carlo alle Quattro Fontane]] (or San Carlino - originally ''Chiesa della Santissima Trinità e di San [[Carlo Borromeo]]''), the first work of this architect as well as the last one: the [[façade]] was completed after his death.
*Palazzo Volpi di Misurata, across from San Carlino, built in the eighteenth century.
*'''Palazzo Albani del Drago''', built by [[Domenico Fontana]] and enlarged with an added belvedere, by [[Alessandro Specchi]] for the [[Albani]] [[Pope Clement XI]]; with the decline in the fortunes of [[Alessandro Cardinal Albani]] it was sold to the del Drago, who occupy it still.
*'''Palazzo Baracchini''', built 1876-83, now housing the Ministry of Defense.
*The church of [[San Silvestro al Quirinale]], which was described for the first time circa [], rebuilt in the 16th century and restructured (façade) in the 19th.
*Villa Colonna (17th century), in front of [[Palazzo Rospigliosi]], contains some remains of [[Caracalla]]'s temple of [[Serapis]]
*The [[Palazzo della Consulta]] hosts today the [[Constitutional Court of Italy|Constitutional Court]], and was erected by [[Ferdinando Fuga]] for [[Pope Clement XII]] directly opposite Palazzo del Quirinale.
