This circuit, active between 1924 and 1961, was the longest circuit ever to feature in the F1 World Championship at 16.032 miles in 1957. Located in the Abruzzi region on the Adriatic coast, the circuit featured two four mile long straights coupled with an eight mile climbing and twisting section. The course also featured level crossings and barely guarded corners. In the thirty-six years the track was open, the track barely changed from Enzo Ferrari's inaugral win in 1924.
