 Cardinal Alfredo Ildefonso Schuster laid the cornerstone on March 14, 1935 and consecrated the Pietro e Paolo church on September 30, 1939.The old church building remained beside the new and was not demolished until 1953, after two keystones broke and large cracks appeared in the wall, which were prohibitively expensive to repair.Between 1928 and 1945 the painter Vanni Rossi adorned the church with a cycle of frescoes.
