Herculaneum Historical Timeline

Herculaneum is a town preserved by the event that erased it. The surviving streets are Roman, but the layers below them and the history of their excavation are part of what visitors are seeing. A traveller descends through modern Ercolano, the excavation terrace and the ancient shoreline in one short route. That vertical relationship is the central fact of the place: the visible town is only a fraction of what the eruption covered.

Chronology

1. 6th–7th century B.C. An early settlement develops on the Bay of Naples; later Greek, Samnite and Roman phases build the town whose streets and houses are visible today. The name and foundation stories are ancient, but the excavated fabric records successive communities rather than one founding moment.
2. 2nd century B.C. The town walls are built in thick masonry. When their defensive role ends, parts are absorbed into houses, so the line survives as building fabric rather than as a complete circuit. The House of the Inn is one visible example of a defensive structure reused by domestic construction.
3. A.D. 79 Vesuvius buries Herculaneum beneath successive hot flows to roughly 20 metres. The deposit destroys lives but seals timber, food, papyri and decorated rooms that can still be seen in the excavated quarter. Unlike the shallower ash at Pompeii, this deep material becomes a protective blanket and a later excavation problem.
4. 1709 A well shaft reaches ancient structures and leads to tunnel searches for sculpture. The first rediscovery leaves galleries underground, a reminder that the modern park is only one layer of the site. Early digging sought valuable objects rather than a complete town plan.
5. 1738 Charles of Bourbon sponsors systematic excavation. Finds are removed to royal collections, including the material that now helps explain Herculaneum at the MANN. The royal project makes the buried town part of European antiquarian culture while separating many objects from their original rooms.
6. 1752 The first Herculaneum papyri are recovered from the Villa of the Papyri. Carbonisation preserves the scrolls but makes them fragile; their presence in Naples is one reason the site cannot be understood only by walking its streets.
7. 1828–1837 Francis I orders renewed excavations and land purchases. The exposed area expands, but the modern town remains over the buried city. Later acquisitions under the Kingdom of Italy extend the excavation eastwards without making the whole ancient settlement accessible.
8. 1927–1942 Amedeo Maiuri excavates about four hectares. The streets, houses and public buildings now form the core of the archaeological park. The route visitors follow is therefore a twentieth-century selection of an older town, not an uncovered city in its entirety.
9. 1980–1981 Excavation of the ancient shoreline and boat houses finds large numbers of victims. The discovery changes the picture from a town whose inhabitants escaped to one where many people waited at the sea. The boat houses remain the most direct physical meeting with that final evacuation.
10. 1996–1999 Excavators bring the Villa of the Papyri, the north-west baths and other buildings to light. The discoveries expand the park’s architectural range while leaving the area vulnerable to weather and unstable edges.
11. 2000–2007 Major conservation work addresses a site left vulnerable after excavation. The present visitor route is therefore both ancient fabric and a modern preservation project. The choice to leave much underground is part of the site’s current history.

What survived, and how

The volcanic cover protected organic material from weather and looting, but exposing it created a new problem: air, light, water and unstable walls accelerate decay. Painted plaster fades when its burial climate disappears; walls that were supported by the deposit need new structural care. The park now leaves much of the town buried and concentrates on stabilising what is open. The closed Villa dei Papiri is a visible reminder that excavation is not the same as preservation. The route’s barriers, shade structures and intermittent closures are conservation decisions made visible to visitors.
