Italy regained possession of the building in 1917 and it was restored. Mussolini had his office in the Sala del Mappamondo, and used a balcony in the palazzo for many of his most notable speeches to people gathered in the Piazza Venezia below.

In the courtyard, on a pathway overhung with myrtle are statues of four children holding shields bearing the names of famous Venetian conquests named Cyprus, Dalmatia, Morea, and Candia. These statues stand at intervals on a long stone bench. And beside the pathway goldfish swim contentedly in and out of the pond plants in a small shallow oval lake. And goldfish swam around their big travertine brothers spraying water from their mouths. In the center, there are three delightful and energetic tritons with their tails in the water leaning against a cluster of rocks. The tritons seem to be trying by sheer strength to hold up a double shell. They look rather like the two tritons at Santa Maria in Cosmedin in their position. On the shell stands the City of Venice wearing a cloak and the pointed hat of the doges. Venice smilingly throws a golden ring into the water in the traditional "Marriage of Venice to the Sea." On one side, the winged lion of St. Mark crouches at her feet. While on the other side, a laughing child clings to her flowing baroque robe holding an unfurled scroll inscribed with a Latin text.

The Palazzo Venezia with its tower rising above the left foreground pines in Piazza Venezia is seen from the observation terrace on the Victor Emmanuel II Monument. The Museo del Palazzo di Venezia is within the building, containing galleries of art, predominantly pottery, tapestry, statuary from the early Christian era up to early Renaissance.
