Pasquale Poccianti

The Cisternoni of Livorno are a series of three large buildings in the neoclassical style at Livorno, in Tuscany, Italy. They were constructed between 1829 and 1848 as part of a complex of purification plants and storage tanks to the Leopoldino aqueduct; a fourth cisternone planned at Castellaccia was never built. The cisternoni, literally "great cisterns", provided Livorno — a city that is still today one of the principal ports of the Mediterranean — with fresh and, more importantly, clean water throughout the 19th and 20th centuries.

Designed by the architect Pasquale Poccianti, the cisternoni are architecturally important, as they represent the advent of an aesthetically considered approach to the design of utilitarian public work. This movement, whose followers are sometimes known as "Utopians", was pioneered by such architects as Étienne-Louis Boullée and Claude-Nicolas Ledoux at the close of the 18th century. The movement resulted in great palaces and temples of industry and commerce, their palatial and temple-like facades concealing the mundane reality of their true use, which were to dominate many towns and landscapes from the 19th century onwards.

The Acquedotto Leopoldino (also known as the "Acquedotto di Colognole") and the neoclassical cisterns of Livorno were part of a sophisticated scheme to not only provide water to Livorno, but also clean it. The scheme was centred on the 18 km (11 mi) long aqueduct which runs south to north bringing water to the city from Colognole. This feat of engineering first carried water to the city in 1816, long before its completion. It was Livorno's sole water supply until 1912, still serving some areas of the city.

The aqueduct was commissioned in 1792 by Ferdinand III, Grand Duke of Tuscany. Construction began in 1793 to plans drawn by the architect Giuseppe Salvetti, replacing an earlier aqueduct constructed in the 16th century by Ferdinand de' Medici. Work stopped in 1799 on the death of Salvetti and, because of the political difficulties and upheavals in Tuscany caused by the first disruptive phases of the Napoleonic occupation of Tuscany, did not resume until 1806, when Maria Louisa, regent of Etruria, acting for her infant son, appointed the architect Riccardo Calocchieri to supervise the work. Later, in 1809, during the French occupation of Tuscany and reign of Elisa Bonaparte, Poccianti was appointed by the newly formed "Comune of Livorno" to oversee the project and under his direction work continued until 1824, the date usually considered as that of the aqueduct's completion. However, modifications were always being implemented, and after Poccianti's death in 1858, the project was continued by his successor Angiolo della Valle.
