Naples Underground Engineering: Aqueducts and Cisterns

Water is the story behind the story. The metropolis dug out cisterns connected by a web of channels. Maintenance was a specialized craft.

How It Worked

1. Collection: rainfall and springs.
2. Filtration: sedimentation in stepped basins.
3. Distribution: channels with inspection shafts.
4. Maintenance: professional well-keepers.

Design Details

• Rounded cistern corners reduce stress points.
• Bridges (ponti) provide full-surface access for cleaning.
• Boreholes (pozzi) function for inspection, airflow, and water control.

Visiting Clues

• Water marks on walls reveal former levels.
• Tool marks show maintenance routines and access methods.
• Sediment bands indicate seasonal use.

Safety & Respect

• Stay on designated walkways.
• Avoid touching damp surfaces; oils can stain.

Bottom Line

Naples engineered hydration in stone — a masterpiece of necessity and ingenuity.
