Church of San Carlino alle Quattro Fontane

The Church of San Carlo alle Quattro Fontane, also known as San Carlino, is one of the masterpieces of Baroque architecture in Rome. Designed by Francesco Borromini and built between 1638 and 1641, the church is located at the corner of via del Quirinale and via delle Quattro Fontane, near the Quirinale Palace. The church is dedicated to San Carlo Borromeo, one of the most important reformers of the Catholic Church. The facade of the church, with its curves and counter-curves, is an extraordinary example of Borromini’s architectural ingenuity. The interior of the church, equally innovative, is characterized by an elliptical plan that creates a great sense of dynamism and movement. Of particular interest is the dome, decorated with a series of geometric shapes that seem to multiply infinitely, creating a surprising optical effect. This dome, with its play of light and shadow, is considered one of the masterpieces of Baroque art. An interesting anecdote concerns the small size of the church, which earned it the nickname “San Carlino alle Quattro Fontane.”
