Piazza De Ferrari, Central square in Portoria, Genoa, Italy.

Piazza De Ferrari is a large public square at the center of Genoa with a prominent bronze fountain in the middle. The square is framed by four important buildings, including a theater and historic palaces.

The square occupies the site of the former Piazza San Domenico, named after a church demolished in the 1820s to build the Teatro Carlo Felice, inaugurated in 1828. In 1877 it was dedicated to Raffaele De Ferrari, duke of Galliera, banker and politician. Its present shape emerged between 1899 and 1923 with four eclectic palaces built after the excavation of Colle Sant'Andrea, and in 1936 the bronze fountain by Giuseppe Crosa di Vergagni was added at its centre.

Genoese call the square "a Ciassa" and measure distances from other cities to it. It hosts political rallies, union and student demonstrations, dance and theatre shows, and football celebrations, when fans dive into the fountain after Genoa, Sampdoria or Italy wins, as after the 1982 and 2006 World Cups.

The square is almost entirely pedestrianised, so you cross it on foot; the fountain sits at its centre, with the Teatro Carlo Felice and the Garibaldi statue on the theatre side and the Palazzo Ducale toward the historic centre. Via XX Settembre, Via Dante and Via Roma branch off from the square, and the De Ferrari metro stop opens onto it.

The bronze basin of the 1936 fountain, designed by Giuseppe Crosa di Vergagni, was donated by engineer Carlo Piaggio to mark Italy's entry into the war against Abyssinia. The fountain was inaugurated on 24 April 1936 and became a city symbol alongside the Lanterna.
