Herculaneum

Herculaneum was a Roman town by the sea in Italy. Long ago, a volcano buried it. Now people can walk through its old streets and houses.

Herculaneum was a small Roman seaside town near Naples, Italy. In AD 79 the volcano Mount Vesuvius erupted and buried it under many meters of volcanic material. That covering kept its houses, upper floors and even wooden furniture so well preserved that archaeologists have been uncovering them since the 1700s.

Buried by pyroclastic surges and flows when Vesuvius erupted in AD 79, Herculaneum, a coastal resort 320 by 370 m within its walls, survives with upper storeys, carbonized wood and food, wax tablets and the papyrus scrolls of the Villa of the Papyri. Found by chance in 1709 and tunneled from 1738, it has been excavated in the open since 1927 and is part of a World Heritage Site inscribed in 1997.

Discover Herculaneum

Herculaneum is in Italy, near the big city of Naples.

It was a small town where Roman people lived about 2,000 years ago. Today a new town, Ercolano, is built right above part of it.

Herculaneum lies beside the Bay of Naples, in southern Italy, at the foot of the volcano Mount Vesuvius. It was a small Roman town, only 320 meters by 370 meters inside its walls. Unlike commercial Pompeii nearby, it was a holiday resort for rich Romans, with fine views of the sea.

Today the ancient town lies in a deep hollow below the streets of the modern town of Ercolano. Much of it is still buried under the modern buildings. Together with Pompeii and the Roman villas at Torre Annunziata, it is a World Heritage Site.

Herculaneum stood on a promontory overlooking the Bay of Naples. ICOMOS describes it as a much smaller town than Pompeii, 320 by 370 m within its walls, laid out on a regular 'Hippodamian' grid at the end of the 1st century BC, with a wide main street that also served as the forum. It had been under Roman rule since 89 BC, and it was a holiday resort for wealthy Romans, where Pompeii was a commercial town.

UNESCO inscribed the 'Archaeological Areas of Pompei, Herculaneum and Torre Annunziata' in 1997 under criteria (iii), (iv) and (v). It notes that large areas of the ancient town, including its theater, still lie under modern Ercolano, known only through 18th-century tunnels; UNESCO's records list minor changes to the property's boundaries in 2023 and 2026.

Buried in AD 79, found in 1709

One day, the nearby volcano erupted.

Hot volcanic material covered the whole town. It stayed hidden for more than 1,600 years, until people digging a well found it.

On 24 August AD 79, Mount Vesuvius erupted. Pompeii was buried mostly under volcanic ash and small stones, but Herculaneum disappeared under fast-moving clouds and flows of hot volcanic material, many meters deep. The area had been shaken by an earthquake a short time before, and some buildings were still being repaired.

The town was found by chance in 1709, when workers digging a well reached the buried theater. In 1738, on the orders of the king of Naples, diggers began to explore it through tunnels. Only in 1927 did archaeologists start to uncover it in the open air.

UNESCO dates the eruption to 24 August AD 79 and says Herculaneum disappeared under pyroclastic surges and flows; ICOMOS describes many meters of volcanic mud, and notes that an earthquake shortly before had left reconstruction still in progress. The depth of burial is why so much less of Herculaneum has been uncovered than of Pompeii: ICOMOS recorded that excavating part of the Villa of the Papyri meant removing more than 25 m of volcanic deposits.

The ruins were discovered by chance in 1709 during the digging of a well, which still survives above the buried theater. Tunnels driven out from the shaft were used to remove art treasures; deliberate excavation, still by tunneling, began in 1738 on the orders of the Bourbon king of Naples. Open-air excavation using methods developed at Pompeii began only in 1927.

Through the years

Preserved by the volcano

The volcano's covering kept things safe for a very long time.

Archaeologists found upstairs rooms, wooden furniture and even old food!

The thick volcanic covering that buried Herculaneum also protected it. Many houses still have their upper floors, which survived much better here than at nearby Pompeii. The great heat turned wood and food into charcoal, so wooden furniture, parts of buildings and everyday foods were preserved.

The volcanic layers also kept hundreds of wax writing tablets, some with legal documents, and more than 1,800 rolls of papyrus, an early kind of paper, in a grand house outside the walls called the Villa of the Papyri.

UNESCO notes that Herculaneum's urban districts and seafront are preserved to a higher level than Pompeii's, with notable conservation of upper floors, thanks to the pyroclastic material that buried the town. High temperatures often carbonized organic matter, preserving foodstuffs, architectural elements and wooden furniture; ICOMOS adds that wood survives in place in many buildings.

The deposits also preserved hundreds of wax tablets, some recording legal documents, and more than 1,800 papyrus scrolls of Greek philosophical texts found at the Villa of the Papyri, an opulent villa outside the walls. ICOMOS noted in 1997 one lasting problem: the coast sank during the eruption, so the site has a high water table that makes conservation harder.

Streets, houses, baths and an ancient shore

In the town are houses, shops and bathhouses.

Some shops still have their giant jars for wine. Down at the bottom are big stone arches where the beach used to be.

Visitors can walk along Herculaneum's paved streets past houses, shops and public buildings. There is a large sports ground, called a palaestra, with a grand gateway, and two sets of public baths, one of them richly decorated. Some shops still hold their equipment, such as enormous wine jars.

In the photo, a row of stone arches runs along the bottom of the town, by what was once the ancient coastline. Above them rise the walls and houses of the old town, and behind, the buildings of modern Ercolano and the slopes of Vesuvius.

UNESCO lists a spacious palaestra entered through a monumental gateway, two sets of public baths (the Central Thermae monumental and vividly decorated) and a theater of standard form, still reached only through the 18th-century tunnels. ICOMOS singles out the House of the Bicentenary, named because it was excavated two hundred years after work first began, and the seafront houses such as the House of the Deer, with large courtyards and rich decoration. Shops survive complete, with equipment such as enormous wine jars.

The arches at the foot of the excavated town stand by the ancient coastline; in July 2026 the park reopened the Martusciello Gallery, a route that brings visitors closer to the arches and the ancient beach. In the 20th century Herculaneum was presented as an 'open-air museum', perhaps Europe's first, in UNESCO's words.

Herculaneum today

Today, Herculaneum is a park where visitors explore.

Mount Vesuvius still stands nearby. Scientists and workers look after the old town.

Today Herculaneum is an archaeological park run by Italy's Ministry of Culture. Visitors walk down into the ancient town, past houses and shops, and look up at the high walls of the excavation, cut through the volcanic deposits that once covered it.

Keeping it safe is hard work. In 1997, experts reported that rain, wind, damp and the high water level under the site were wearing away the old buildings, and that an earthquake in 1980 had made some problems worse.

The site is managed as the Archaeological Park of Herculaneum under Italy's Ministry of Culture. ICOMOS, in its 1997 evaluation, described serious structural problems at both Herculaneum and Pompeii from inappropriate materials, rising damp, and rain and wind, worsened by the 1980 earthquake, and at Herculaneum the high water table. It also praised the placing of copies and casts of paintings and sculptures, now in the Naples museum, back where they were found, as in the House of the Deer.

The photo shows the excavated town in its hollow, the arches by the ancient shore, a stairway and terraces, modern Ercolano above and Vesuvius on the skyline.

    UNESCO and ICOMOS both note the completeness of the town's shops, with equipment such as enormous wine jars still in place.

  • One house is named after a big birthday of the dig.

    The House of the Bicentenary got its name because it was dug out 200 years after work at Herculaneum first began.

    The House of the Bicentenary was so named because it was excavated two hundred years after work first began at Herculaneum.

  • Herculaneum may have been Europe's first open-air museum.

Talk about it

  • Why might a covering of volcanic material keep wood and food from rotting away?
  • Much of Herculaneum lies under a modern town. Should it be dug up? What would be gained and lost?
  • What could written scrolls tell us that buildings cannot?

Try at home or in class

  • Bury a few small objects in a tray of damp sand, let it dry, then dig them out carefully with a spoon and brush like an archaeologist.
  • Draw a cross-section showing the modern town on top, the volcanic layers in the middle and the Roman town at the bottom.
