Two temporary wooden flag poles were installed in the Piazza Unità d’Italia, Trieste, in 1923. The Royal Automobile Club of Italy replaced them with bronze ‘pylons’ in 1933. The pylons are 6 meters high; the sculptural bases, from a sketch by Attilio Selva (1888-1970), are 4.25 meters high and are tributes to Italian losses in the First World War.
