Santa Maria dei Miracoli and Santa Maria in Montesanto

Santa Maria dei Miracoli and Santa Maria di Montesanto are two churches in Rome.

They are located on the Piazza del Popolo, facing the northern gate of the Aurelian Walls, at the entrance of Via del Corso on the square. The churches are often cited as "twin", due to their similar external appearance: they have indeed some differences, in both plan and exterior details.

Looking from the square, the two churches define the so-called "trident" of streets departing from Piazza del Popolo: starting from the left, Via del Babuino, Via del Corso and Via di Ripetta. The first two are separated by Santa Maria in Montesanto, the latter by Santa Maria dei Miracoli.

The origin of the two churches traces back to the 17th-century restoration of what was the main entrance to the Middle Ages and Renaissance Rome, from the Via Flaminia (known as Via Lata and Via del Corso in its urban trait). Pope Alexander VII commissioned the monumental design of the entrance of Via del Corso to architect Carlo Rainaldi. This included two churches with central plans, but the different shapes of the two areas available forced deep modifications to the projects.

Both were financed by cardinal Girolamo Gastaldi, whose crest is present in the two churches.
