Church of San Carlo alle Quattro Fontane
The Church of San Carlo alle Quattro Fontane is a baroque church built between 1634 and 1644 by Francesco Borromini. The facade of the church on the street was designed and built much later, from 1664; after the architect's death in 1667, the work was continued from 1670 to 1680 on the basis of Borromini's drawings.
