Sixtus V was extremely fond of this portion of the city and with Fontana's assistance he created the magnificent palace and surroundings which ever since his day have been associated with sovereign power in Rome. Fontana enlarged the piazza before the palace in order to make it “commodious for consistories/ 9 and he also lowered the grade in order to bring hither the Acqua Felice.
Rome was metamorphosed into a republic, but this obscuration of the papal power was only temporary. When Pius VI died, at Valence, in August, 1799, the cardinals held their Conclave at Venice, and on March 14, 1804, elected Pius VII who returned to Rome the following July. This was the Pope who, after many misgivings, consented to crown Napoleon. Five years later, when the Emperor proceeded to annex the Papal States to his empire, this was the Pope who excommunicated him.
In the quiet sunset of his days, which outlasted by two years the life of the great conqueror, the Pope had time to erect the fountain of Monte Cavallo, and to begin or continue the architectural and archaeological projects connected with his name.
