Piscina Mirabilis, Ancient Roman cistern in Bacoli, Italy
The underground reservoir measures 70 meters in length, 25 meters in width, and features 48 cross-shaped pillars arranged in four rows forming five naves.
Built during the Augustan period, this water storage facility served as the terminal point of the Aqua Augusta aqueduct, supplying water to the Roman fleet in Miseno.
The name Mirabilis originates from Italian poet Francesco Petrarca, who described the structure as admirable during his visit to the archaeological site.
Visitors can access the cistern through a metal staircase at the northwest entrance, which protects the original Roman steps from wear and tear.
The reservoir contained 12,000 cubic meters of water and utilized a sophisticated system of hydraulic machines to channel water toward the port of Miseno.
