The stream is now buried under Via Brigate Partigiane Sixteen proposals were submitted, and the jury chose the draft by the architect Marcello Piacentini and the sculptor Arturo Dazzi.

The commission chose it because the design was inspired by Imperial Roman and 16th century architecture, giving the monument a strong, heroic and triumphant appearance.

In the sanctuary, there are some statues by sculptor Giovanni Prini representing Victories, Saint George and the coat of arms of Genoa.

Two large columns are located inside the arch, and they support lunettes sculpted by Prini dedicated to peace and the family.

The exterior of the monument is decorated with allegories sculpted by Dazzi and Mario Maria Martini, which commemorate the 680,000 Italians killed in World War I and the construction of the arch.
