Terzo Polazzo was an Italian architect, painter and sculptor. He worked in Roma and Padova. With other architects in 1939 he designed the headquarters of the Italian NOC (CONI) with its extreme glass facades. He was also active as a book illustrator, and sculptor modeling busts and figures as well as a painter and furniture designer.
Polazzo caused attention in 1948 with his monograph, From Castel S Angelo to the Basilica of St. Peter, followed by historical artistic research by Bernini on the demolition of the "Spina". Polazzo designed a detailed original project for the path of conciliation with the construction of a "Portica" including framing waves from former Michelangelo's dome. Another original idea of Polazzo in 1974 was a solution to get around the Colosseum with a causeway, creating a pedestrian tourist area between the Colosseum, the Arch of Constantine and the Roman Forum.
