Rebuilt by Leo III in the 9C and restored in the late 15C by Sixtus IV, the church's current appearance dates from the 16C. Completed in 1603, the façade is a harmonious masterpiece by Carlo Maderno (1556-1629), who was inspired by the façade of the Chiesa del Gesù, an archetype of the Counter-Reformation style. Its austere façade features colonnettes and employs the play of light, diffused by niches and pediments.
