Santa Maria del Popolo
The architect or architects of this innovative project remain unknown due to a lack of contemporary sources. Giorgio Vasari in his "Lives" attributed all the important papal projects in Rome during Sixtus IV to a Florentine, Baccio Pontelli including the basilica and monastery of Santa Maria del Popolo. Modern researchers deemed this claim highly dubious and proposed other names among them Andrea Bregno, a Lombard sculptor and architect whose workshop certainly received important commissions in the basilica. The fundamental differences between the façade and the interior suggest that maybe more than one architect was working on the building.
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.
