Santa Maria dei Miracoli and 
Santa Maria in Montesanto are two 17th century churches located on the Piazza del Popolo, facing the northern gate of the Aurelian Walls, at the entrance of Via del Corso on the square. 
 For reference, a plan of the church is available 
here.
 
    
The twin churches were built on the orders of 
Pope Alexander VII after his predecessors had
constructed the 
Piazza del Popolo. The first architect was 
Carlo Rainaldi, and work was continued by 
Carlo Fontana. The church is served by the Priests of the Sacred Heart.
