San Carlo alle Quattro Fontane, also known as San Carlino - the church in Rome, built by the architect Francesco Borromini. It is considered a masterpiece of Baroque architecture and is part of the monastery buildings on the Quirinal Hill, erected for the Spanish Catholic Trinitarian Order. Barberini received an order for construction of the church in 1634 by Cardinal Francesco Barberini Palace, which is across the street. However, financial support for the Cardinal was short-lived, and in the course of construction of the church workers are faced with a shortage of funds.

Five years later, the church was consecrated in honor of Saint Carlo Borromeo.

Nearby stands the church of Sant'Andrea al Quirinale by Bernini.
