The church of San Carlo alle Quattro Fontane is dedicated to the Holy Trinity and to St. Charles Borromeo.
Francesco Borromini (1599-1667) came to Rome when he was 20 years old to work at St. Peter’s for his architect uncle, Carlo Maderno, and Bernini. Borromini did not get his own architectural commission until he was 35, when the Order of the Holy Trinity asked him to build a monastery and then a church for their property on the Quirinale Hill.
It is difficult for me to put into words a short description of either the interior or the exterior of San Carlo alle Quttro Fontane. I hope these pictures and quotes will allow you to enjoy “San Carlino.”
One of the most subtle and original buildings of the Roman Baroque, and a source of endless pleasure for anyone who enjoys the play of space, light and texture in architecture. A masterpiece by one of Italy’s most unusual designers and a work so skillfully integrated into a given piece of Rome’s monumental townscape. John Wilton-Ely (Art historian, Fellow of the Society of Antiquaries, London, and Royal Society of Arts)
This is a complete work of sculpture masquerading as a building. The contrapuntal rhythm of its curves and the complete inversion of interior and exterior space is breathtaking. The building shows that the distinction among painting, sculpture and architecture disappear in the work of a great artist. Waltar Chatham (Architect, New York City)
