Mazzoni was born in
Bologna and was moved to
Rome in 1905 with his parents, but returned to the
Academy of Fine Arts, Bologna, for his education. In 1920, Mazzoni practiced for about a year under
Marcello Piacentini. The following year, he was engaged as an engineer with the Special Section of Railway Workers in
Milan, then rose to a position in the newly formed
Ministry of Communications in 1924, producing significant independent work by 1926. Politically astute, Mazzoni also joined the
National Fascist Party in 1926. He owed much of his success and influence to his intimate connections with the Fascist regime, and played a decisive role in using architecture to consolidate positive images of Fascism. The Fascist regime engaged in a comprehensive national program of public works. As chief architect for the Ministry of Communications and for the State Railways, both key modernizing sectors of Fascist rebuilding programs, Mazzoni designed many of them. Italy still contains hundreds of its large and small railway and telecommunications buildings, extant and functioning, a tribute to its mastery of robust, hard-working construction. In many of these, he collaborated with architect and engineer
Roberto Narducci. Mazzoni's relationship with Fascism made it politically difficult for subsequent scholars to acknowledge his importance. Construction on his major commission, the vast
Roma Termini railway station, was suspended in wartime Italy and redesigned by others after the Fascist defeat. Other important buildings by Mazzoni were crudely altered or demolished in the post-war period. His own personal advocacy of Fascism worked against his legacy, even after the end of
World War II, when he voluntarily exiled himself in
Bogotá, Colombia, until 1963. More recently, academics and scholars such as Ezio Godoli, Giorgio Muratore, and Enrico Crispolti have begun a rehabilitation process and a critical re-evaluation of Mazzoni. His archive is now kept at the Museum of Modern Art in Trento, and efforts are being made to ensure the conservation of his most important surviving buildings. == Works ==
