Herculaneum is one of the best-preserved Roman towns in the world, sealed in 79 AD when Vesuvius sent pyroclastic surges — superheated avalanches of gas and rock — pouring down the mountainside. Unlike Pompeii, which was buried under metres of pumice, Herculaneum was entombed in volcanic material that carbonised wood, cloth, and food rather than simply smashing them. The result is extraordinary: wooden beams, doors, beds, and furniture have survived nearly two thousand years.
The site is much smaller than Pompeii — only about a third has been excavated, the rest buried under the modern town of Ercolano — which makes it easier to navigate and far less crowded. The streets are narrow, the buildings two and three storeys high, and the mosaic floors, painted walls, and stone counters feel remarkably close to the day they were abandoned.
Entry is around €15; combined tickets covering Pompeii, Oplontis, and other Vesuvian sites offer good value. Opening hours are 9am–7:30pm April–October, 9am–5pm November–March (last entry 90 minutes before closing). Allow 2–3 hours minimum.
