Pompeii was destroyed in 79 CE when Mount Vesuvius erupted and buried the city under ash, pumice, and hot volcanic debris. Many residents died from falling material and pyroclastic surges, and the burial later preserved the city’s buildings and artifacts for centuries.

Quick Scoop

  • What happened: A massive eruption from Mount Vesuvius overwhelmed Pompeii.
  • When: 79 CE, with ash fall beginning on August 24 and deadly pyroclastic surges following on August 25.
  • Why it matters: The city was sealed under volcanic material, which is why archaeologists later found it so remarkably preserved.

In simple terms

Pompeii was a busy Roman city near Naples, but the eruption turned it into a buried ruin almost overnight. The disaster was tragic, but it also froze a snapshot of ancient Roman life in place, making Pompeii one of the world’s most famous archaeological sites.
