Construction of this elegant terrace overlooking the sea, where a splendid view of the islands of the Tuscan Archipelago and Corsica can be admired, was begun in 1925. In 1945 it was named after Livorno’s famous composer Pietro Mascagni. It is extremely popular during summer evenings, with the added attraction of the chalet cafes along the promenade.

It was built in an area known as Spianata dei Cavalleggeri after a military fort erected there to defend the coast, and destroyed in 1866. During the Belle Époque, as part of a plan to renovate the sea-front for tourism and sea-bathing, the area underwent a radical transformation, becoming the site of one of the biggest permanent fairgrounds – the Eden Rollercoaster, inaugurated on 5 July 1892. In the summer of 1896, the Lumiere Cinema was opened at the Eden, and Livorno became one of the first cities in Italy to welcome the new invention.

By 1918 the attractions which made up the Eden had already disappeared, and a new building used as a sun treatment holiday camp appeared.

Construction of the Terrazza as a public space began between 1925 and1926. It was later enlarged and completed in 1928 by engineers Salvais and Pastore and named after the Fascist party leader, Costanzo Ciano. 

In 1935 a gazebo, used for musical performances, was added. Destroyed by bombing, it has recently been entirely rebuilt. The aquarium, situated in the centre of the large parterre, was inaugurated in 1937 – it was also destroyed during the last war and was rebuilt during the fifties.
