One of the most fascinating types of churches in Rome are the titular churches — churches that were once house-churches, and still today...

At the intersection of four Roman streets, each corner features a fountain with a river god or symbolic figure. The site sits directly between Santa Maria Maggiore and the Spanish Steps, with obelisks visible at both ends — a product of papal urban planning. Don’t miss San Carlo alle Quattro Fontane, Borromini’s unforgettable little church tucked into one corner.
