The result of a participatory planning process, "Piazza Don Gallo" is the application that accompanies the discovery of the San Benedetto al Porto district and of one of the characters who most recognized the dignity of the place and of the people who live there: Don Gallo . The app offers reproductions of paper documents, photographs, original videos, interviews and descriptive texts. Thus, the story of San Benedetto del Porto and Don Andrea Gallo is retraced through the testimonies of a "princesa", of the parish priest who welcomed him and of many other people who lived and shared Don Gallo's commitment.
