Bolla Aqueduct

The Bolla Aqueduct was an ancient underground water system in Naples, constructed around 400 BC by Greek colonists [1]. The structure extended approximately 10 km (6.2 miles), channeling water from the Volla plain near Mount Vesuvius—a marshy depression [1]. Water entered Naples at Porta Capuana before distributing through underground channels to private wells throughout the city [1].
