In the 16th century Sixtus V bisected Bramante's Cortile del Belvedere with a cross-wing to house the Apostolic Library in suitable magnificence.

A visit to the villa of Cardinal Luigi d ' Este in 1573 convinced Pope Gregory XIII to start the building of a summer residence the following year, in an area considered healthier than the Vatican Hill or Lateran: His architects were Flaminio Ponzio and Ottaviano Nonni, called Mascherino ; under Pope Sixtus V, works were continued by Domenico Fontana ( the main facade on the Piazza ) and Carlo Maderno, and by Gian Lorenzo Bernini for Pope Clement XII.

The Pope set no limit to his plans, and achieved much in his short pontificate, always carried through at top speed: the completion of the dome of St. Peter's ; the loggia of Sixtus in the Basilica di San Giovanni in Laterano ; the chapel of the Praesepe in Santa Maria Maggiore ; additions or repairs to the Quirinal, Lateran and Vatican palaces ; the erection of four obelisks, including that in Saint Peter's Square ; the opening of six streets ; the restoration of the aqueduct of Septimius Severus (" Acqua Felice "); the integration of the Leonine City in Rome as XIV rione ( Borgo ).

Sixtus had, however, no appreciation of antiquities, which were employed as raw material to serve his urbanistic and Christianising programs: Trajan's Column and the Column of Marcus Aurelius ( at the time misidentified as the Column of Antoninus Pius ) were made to serve as pedestals for the statues of SS Peter and Paul ; the Minerva of the Capitol was converted into an emblem of Christian Rome ; the Septizonium of Septimius Severus was demolished for its building materials.
