Marcel Meili and Christoph Schaub tell the story of 'Il Girasole', the rotating modernist house built into the Po Valley hillside in northern Italy, in this award-winning film.  Affectionately termed 'The Sunflower', the house was built in the 1930s by architects Angelo Invernizzi and Ettore Fagiuoli, with the help of their artist, sculptor, designer and architect friends.
