heliotherapy centre in the early 1900s. A new parterre, built between 1925 and 1928 by Enrico Salvais and Luigi Pastore, was formed by a series of flower beds and a walkway which follow the outline of the sea with numerous balustrades named after Costanzo Ciano. The Terrazza has a paved surface of 8,700 square meters formed by 34,800 black and white tiles placed as a checkerboard and 4,100 balusters. In 1932, a gazebo for musical performances was built in the large square; it was destroyed during World War II. In 1937 the Livorno Aquarium was constructed. After the war, the Terrazza was dedicated to Pietro Mascagni and in 1994 it underwent a complete restoration using the same kind of materials originally employed; the works were completed on 10 July 1998 with the reconstruction of the gazebo. Palazzo Comunale Livorno was elevated to the status of city on 19 March 1606 by Ferdinando I de' Medici, the first Gonfaloniere Bernardetto Borromei and the Community representatives held their meetings in the Church of Saint Mary and Saint Julia. On 13 June 1646 a building, placed in Via del Porticciolo, was purchased for the sum of seven thousand ducats, in order to accommodate the Community. It was evident that it was inadequate to the task and the Council deliberated, on 27 January 1720, the construction of the new town hall on the project by Giovanni del Fantasia. The new neo-renaissance palace, positioned between Palazzo della Dogana and Palazzo Granducale on the north side of Piazza d’Arme, was partially destroyed by the 1742 earthquake. Restored in 1745 by Bernardino Ciurini and Antonio Fabbri a double white marble stairway and a small bell tower on the top of the façade were added. In 1867 the complex was enlarged with the acquisition of three other buildings in the back. With the settlement of the Podestà in the fascist period was carried out a new enlargement in 1929 by Enrico Salvais and Luigi Pastore transforming the adjacent former fire station in the council hall. Damaged by the bombing during World War II it was rebuilt and renovated under the direction of Primavera and was inaugurated in 1949 by the mayor Furio Diaz.
