The twin churches called Santa Maria dei Miracoli and Santa Maria in Montesanto view from Poazza del Popolo.Those were originally intended to be mirror images of each other but the space available for each was slightly different. To compensate the architects used some tricks such as an oval dome on S. Maria in Montesanto to make the facades appear identical to viewers in the Piazza You can see the father dressed one guy posing for photo.I could manage to capture him during my visit there
