[1][2] The circuit was created in 1921 at the initiative of Paolo Fabbrini, owner of the newspaper Corriere di Livorno to host local sports car races.

The circuit was long, with dangerous sections and extremely hard on both man and machine but considered a huge success, attracting interest from regional motoring clubs and the automobile industry alike.

Like many other circuits of the era, Montenero had to change its layout several times over the years to accommodate the growing demands of racing technology.

The last major Circuito Montenero - Coppa Ciano Grand Prix in 1939 also marks the end of the great road course era.

Safety concerns, increasingly unmanageable circuit demands, faster cars among other factors left shorter, purpose-built race tracks as the only viable alternative for future Grand Prix venues.
