Piazza Unità d'Italia

Piazza Unità d’Italia opens onto the Gulf of Trieste on its seaward side and is enclosed on the other three by the monumental buildings of the city centre. The square’s façades reflect Trieste’s history as a major Adriatic port and include the Government Palace, the Assicurazioni Generali and Lloyd Triestino buildings, and the Town Hall.

Why it matters

The square occupies the site of the old mandracchio, the harbour basin between the piers. After the basin was filled in the mid-nineteenth century, the city built the monumental ensemble that now faces the Gulf. Trieste’s tourism portal describes the square as the largest in Europe opening directly onto the sea. It is also a civic gathering place, known historically as Piazza Grande.

What to notice

Blue lights set into the paving mark the former reach of the water. The Town Hall stands at the centre of the landward side, among the buildings that represent Trieste’s commercial and civic institutions. In front of it is the Fountain of the Four Continents. Beyond the seaward edge, the Molo Audace extends more than two hundred metres into the Gulf, with views toward San Nicolò, the Canal Grande and, in clear weather, Miramare.

Context and history

The square has borne several names: Piazza San Pietro, after a chapel that once stood here; Piazza Grande from 1863; and Piazza Francesco Giuseppe under Austrian rule. In July 1914, the ship carrying the bodies of Archduke Franz Ferdinand and Sophie docked here. On 3 November 1918, crowds greeted the destroyer Audace and the arrival of Italian forces. On 18 September 1938, Mussolini proclaimed the racial laws from the square; a plaque installed in 2013 records the event. The city celebrated the return of Italian troops in October 1954, and the square took its present name after Trieste’s definitive return to Italy.
