Santa Maria del Popolo
The Parish Basilica of Santa Maria del Popolo () is a titular church and a minor basilica in Rome run by the Augustinian order. It stands on the north side of Piazza del Popolo, one of the most famous squares in the city. The church is hemmed in between the Pincian Hill and Porta del Popolo, one of the gates in the Aurelian Wall as well as the starting point of Via Flaminia, the most important route from the north. Its location made the basilica the first church for the majority of travellers entering the city. The church contains works by several famous artists, such as Raphael, Gian Lorenzo Bernini, Caravaggio, Alessandro Algardi, Pinturicchio, Andrea Bregno, Guillaume de Marcillat and Donato Bramante.
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.
