Twenty metres beneath the modern town
The ancient theatre of Herculaneum
The theatre of Herculaneum isn't visible from the excavation area: it's still buried, and you visit it by descending tunnels cut by Bourbon engineers in the 18th century. It's the strangest thing you can do here.

Why it's still buried
In 1709 a well dug in search of water struck the theatre's stage wall. Decades of tunnel excavation followed: statues, marbles and inscriptions were hauled out through galleries while the building itself stayed under the volcanic mass. Meanwhile the modern town grew above it — uncovering the theatre would mean demolishing the town.
- Bourbon tunnels you can still walk, pick marks visible on the walls
- The shape of the cavea and stage readable by torchlight
- Dedicatory inscriptions naming the magistrates who funded the building
- The spot where the equestrian statue of Marcus Nonius Balbus was found
Tips for the visit
- Constant temperature and high humidity: bring a layer even in August.
- Narrow, dark spaces: not advisable if you're claustrophobic.
- Closed shoes required — the floor is damp and uneven.
- Flash photography is often prohibited: check on site.
Frequently asked questions
Is the theatre included in the excavation ticket?
No, it has its own access and booking, with a calendar published by the Park.
How long is the visit?
Around 40 minutes, entirely underground.
Is it accessible?
No: there's a long staircase down and the tunnels are narrow.
Do you see the cavea like an open-air theatre?
No. You walk galleries cutting through the structure — you sense the shape rather than see it.
Is it worth it?
Yes if the history of 18th-century excavation interests you; it's a different experience from the surface route.
