Sant'Andrea della Valle
Carlo Maderno (Maderna) (1556 – 30 January 1629) was an Italian architect, born in today's Ticino, who is remembered as one of the fathers of Baroque architecture. His façades of Santa Susanna, St. Peter's Basilica and Sant'Andrea della Valle were of key importance in the evolution of the Italian Baroque. He is often referred to as the brother of sculptor Stefano Maderno, but this is not universally agreed upon.
