The Cisternone of Livorno, also known as the Great Cistern, is a monumental masterpiece of Neoclassical hydraulic engineering built between 1829 and 1842. Designed by architect Pasquale Poccianti, it served as the heart of the Leopoldino Aqueduct system, ensuring a continuous supply of filtered water to the growing Mediterranean port city.
The interior is a breathtaking space covering an area of approximately 1,900 square meters, measuring roughly 45 meters in length and 42 meters in width. It features a “subterranean” forest of 128 pillars arranged in eight rows, which support a series of cross vaults reaching an impressive height. This vast basin can hold approximately 10,000 cubic meters of water. Unlike ancient Roman cisterns, the Cisternone incorporated an innovative purification system, where water from the Colognole springs was filtered through layers of gravel and charcoal to ensure its purity before distribution.
The reservoir is renowned for its metaphysical atmosphere, where the reflection of the columns in the still, dark water, combined with the dim light filtering through the high windows, creates a silent, temple-like environment. Still partially operational today under the management of the local water utility, this ‘Water Cathedral’ remains a rare bridge between the functional needs of 19th-century urbanism and the aesthetic grandeur of ancient Roman engineering.
