Santa Maria del Popolo
In the Julian era the church became again the location of important papal ceremonies. The pope launched his first campaign here on 26 August 1506 and when he returned to Rome after the successful Northern Italian war, he spent the night of 27 March 1507 in the convent of Santa Maria del Popolo. On the next day Julius celebrated High Mass on Palm Sunday in the church that was decorated with fronds of palm and olive branches. The ceremony was followed by a triumphal entry into the city. On 5 October 1511 the Holy League against France was solemnly proclaimed in the basilica. On 25 November 1512 the alliance of the pope with Emperor Maximilian I was also announced in this church in the presence of fifty-two diplomatic envoys and fifteen cardinals. The pope also visited the Madonna del Popolo for private reasons like when he prayed for the recovery of his favourite nephew, Galeotto Franciotti della Rovere in early September 1508.
Piazza del Popolo
To the north of the piazza stands the Porta del Popolo, beyond which lies the Piazzale Flaminio and the start of the Via Flaminia. The gateway was reworked to give its current appearance by Bernini for Pope Alexander VII in 1655, to welcome Queen Christina of Sweden to Rome following her conversion to Roman Catholicism and her abdication. Opposite Santa Maria del Popolo stands a Carabinieri station, with a dome reflecting that of the church.
In his urbanistic project, Valadier constructed the matching "palazzi" that provide a frame for the scenography of the twin churches and hold down two corners of his composition. He positioned a third palazzo to face these and matched a low structure screening the flank of Santa Maria del Popolo, with its fine Early Renaissance façade, together holding down the two northern corners. Valadier outlined this newly defined oval forecourt to the city of Rome with identical sweeps of wall, forming curving exedra-like spaces. Behind the western one, a screen of trees masks the unassorted fronts of buildings beyond.
