The Villa Albani (later Villa Albani-Torlonia) is a villa in Rome, built on the Via Salaria for Cardinal Alessandro Albani. It was built between 1747 and 1767 by the architect Carlo Marchionni in a project heavily influenced by otherssuch as Giovanni Battista Nolli, Giovanni Battista Piranesi and Johann Joachim Winckelmannto house Albani's collection of antiquities, curated by Winckelmann. The villa has been conserved intact into the 21st century by the Torlonia Family, who bought it in 1866. In 1870, the treaty following the Capture of Rome from the Papal States was signed here. History Planned in 1743, the building of the villa began in 1747 according to Giuseppe Vasi and was celebrated as complete in 1763. Its purpose was to house Cardinal Albani's evolving and renewed collections of antiquities and ancient Roman sculpture, which soon filled the casino that faced the Villa down a series of formal parterres. The villa with its collection, fountains, statues, stairways and frescoes, and Italian-style garden, the hemicycle of the Kaffeehaus, constitutes a sublime testimony of that particular antiquarian taste which came to the fore in mid-18th-century, that for which Rome had become a key destination on the Grand Tour. While the Cardinal was the real director of works, for the layout of the works Albani's lifelong friend Carlo Marchionni was the architect in charge, at the Villa and perhaps also for the two temples in the park, an Ionic temple of Diana and a sham ruin. It is hypothesized that Marchionni took advice from Johann Joachim Winckelmann, who at that time, having been hired as librarian by the Cardinal (1759), was creating a catalogue of the collections of antiquities of his patron, paving the way for the reappraisal of Greek art. Winckelmann was a notable force behind the enlargement of the collection, and as he would write in a letter dated August 1766, in the construction process, Albani always adopted Descartes’s maxim not to leave any space empty. And so, in the Sala di Antinoo, the famous relief of Villa Adriana embellished the fireplace, and this room also hosts the famous fresco of Parnassus (1761), created by Anton Raphaël Mengs for the vault of the Galleria, which would go on to become the pictorial manifesto of the nascent neoclassical style. Winckelmann was supported by Albani from the time when the Seven Years' War stranded him in Rome without his pension, and whose own connoisseur
