In 79 CE, the Roman city of Pompeii was destroyed when nearby Mount Vesuvius erupted violently, burying the city under thick layers of ash and pumice and killing thousands of inhabitants. The ash preserved buildings, objects, and even body shapes in such detail that Pompeii became a unique time capsule of everyday Roman life.

The eruption itself

  • On 24 August 79 CE, Vesuvius began ejecting ash, pumice, and gases high into the air, with debris raining down on Pompeii for many hours and collapsing roofs and structures.
  • By the next day, fast-moving pyroclastic surges—scorching clouds of ash, gas, and rock—swept through the city, making survival almost impossible for anyone still there.

How people died

  • Many residents were first trapped or injured as pumice and ash built up, blocking streets and causing buildings to fail.
  • Most victims are thought to have died from asphyxiation and extreme heat during pyroclastic flows, which buried them in ash that later hardened, leaving voids where their bodies decomposed.

What was preserved

  • The city was entombed under several meters of volcanic material, sealing homes, shops, streets, frescoes, and graffiti in place for centuries.
  • When excavations began in the 18th century, archaeologists uncovered detailed snapshots of daily Roman life, including food remains, tools, and the plaster casts made from body-shaped cavities in the ash.

Pompeii today

  • Pompeii is now one of the world’s most visited archaeological sites, offering crucial evidence about Roman urban planning, religion, and social life.
  • Ongoing excavations and scientific studies continue to refine understanding of the eruption’s timeline, the victims’ final moments, and how the city functioned before its destruction.

TL;DR: Pompeii was a thriving Roman city suddenly destroyed in 79 CE when Vesuvius buried it under ash and deadly pyroclastic surges, killing thousands but preserving the city as an extraordinary archaeological record.
