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.
There are more than 930 churches in Rome, which makes it the city with the largest number of churches in the world. Almost all of these are Catholic.
When including the churches that have been deconsecrated or otherwise transformed, the total figure rises to about 1,500 churches.
Santa Maria in Montesanto is a titular minor basilica church in Rome, in the Rione Campo Marzio, which stands in Piazza del Popolo, between Via del Corso and Via del Babuino. It is also known as the Church of the Artists (Chiesa degli artisti). The church is popularly known as the twin church of Santa Maria dei Miracoli, though it shows significant differences especially in the planimetry.
