The Mille Miglia was an open-road endurance race which took place in Italy twenty-four times from 1927 to 1957 (thirteen before the war, eleven from 1947).
Like the older Targa Florio and later the Carrera Panamericana, the Mille Miglia made Gran Turismo (Grand Touring) sports cars like Alfa Romeo, Ferrari, Maserati and Porsche famous.
