The flagpoles of Piazza Unità d’Italia are made up of 6 meter high piles that support the 25 meter antennas on which the two halberds, the city’s coat of arms, of duralumin are placed.

The sculptural part, commissioned to the Trieste sculptor Attilio Selva, is 4.25 meters high and represents the drivers, who fought in the First World War, while they stand guard over the banners of Trieste and Italy. They were inaugurated on 24 May 1933 in the presence of the Duke of Aosta Amedeo di Savoia.
